Windows phone - You have installed the maximum number of development app

I have a windows app that's running for a while and recently when I'm trying to deploy the application on windows phone running windows 8.1 OS(using visual studio 2013 and windows phone application deployment) I'm getting the following error:
"You have installed the maximum number of development apps. These apps are installed to your device when you start them in Visual Studio or when you use the App Deployment Tool. Please uninstall one of them and then try again."
I've tried to reset the phone, renaming the app and the phone on windows explorer, unregister & register the phone and also uninstalling all the other applications on it.
The problem is happening on two different devices Nokia Lumia 630 & Nokia Lumia 920.
Is there another way to approach this?
Thanks in advance
This issue has been fix now and we can register our Windows Phone 8.1 for developing:
Could you please try to unregister the Phone from the Dev Center and register Phone again to see if it works?

can't install company app Codename One windows phone

I am successfully able to create and download build from CN1 server for Windows 8.
I am also able to unlock my windows phone (Microsoft Lumia 640 Windows OS 8.1) using 'Windows Phone Developer Registration' utility.
See below image.
But still I am getting this error, any suggestion please ?
For a testing sake, I created one dummy app just having textfields and even that simple one didn't work.
Thanks.
To run your app on windows phone 8, you have to do the following:
You must be a registered developer.
The phone must be registered.
The phone must be connected to the host computer with the USB cable,
turned on, and the screen must be unlocked.
To test apps on a Windows Phone 8 device:
The Windows Phone IP over USB Transport service must be running. This
service is installed and started when you install the Windows Phone
SDK 8.0.
The computer must recognize the connected device. A Windows Phone 8
phone is listed as a drive in File Explorer.

Unable to register my Lumia 1020 as a testing phone for windows phone apps

I have a Nokia Lumia 1020 that I need to register as a testing device for my Windows Phone Apps. It is running Lumia Cyan thus Windows 8.1. I have Windows Phone SDK 8.1 and 8.0 installed on my machine and when I try to use the Windows Phone Developer Registration (8.1) interface or the normal one (Windows Phone Developer Registration unde Windows Phone SDK 8.0 i keep getting the same error. Unable to connect to a Phone. Make sure that the Windows Phone IP over USB Transport Service is running. I try to restart the service, switch ports, switch from Wi-Fi to 3G network on my phone. Nothing works. I have ensured that the Phone is showing as a device under File Explorer and when I connect the phone to my computer it does launch the Windows Phone app for desktop well. I am not sure what to do at this point and it's getting frustrating. I have tried to reinstall the SDKs and still nothing. I do have a developer account and developer account details intact. Please help... someone.... anyone :(
I finally figured it out. I went to device manager and found under Universal Serial Bus Devices and found device drivers of my phone on all the ports where I had connected the USB cable. I then right-clicked on one that showed that needed an update. I clicked on update device driver software where it scanned for updates and found out that the driver was up to date then I realized that it was not enabled. I enabled it and it was able to recognize the phone. However I had to keep restarting the service since the software kept going offline as well as switching from 3G to Wi-Fi. And it finally worked :)

Have you ever tried to deploy your app to an Windows Phone Emulator?
If your app succesfully deploying to Emulator, I can say your connection of your phone is having problem. But, if you can not deploy your app neither phone nor emulator, it could be about VS2012 or SDK.
So, I sugges you to remove your phone from your computer (Open Device Manager and remove your app (dont forget to unplug it). And then reconnect your phone again.
So, try these and please tell me the results. I was had some problems like yours.
And also, maybe you can check your device's registration status (developer registration) If yes, please try unregister and register it againg for development (http://prntscr.com/2fehv1)
Do a soft reset to your device and restart VS2012 again to solve this problem. (To do this: press and hold the power button and volume down button for about 10 seconds)

How to test a “.xap” file on a Windows Phone 8 device?

Please tell me how I can testing a .xap file on a Windows Phone 8 device? Can I install XAP file on WP 8 without SDK8?
By testing on WP8, I think you mean deploying your app to a physical device. For this you need two things:
dev-unlock your phone. You can do this if you have signed up for an MSDN dev account, or know someone who has
Deploy your application to your device by plugging your phone in to your PC, PIN-unlocking it, and setting the target to Device in
