Application closing when Activating the Connection on FireDAC - mysql

Question

I developed an application that uses FireDAC to connect to a MySQL Database.
But when I try to open it on a workstation, at the moment that I set the Connected := True; on the TFDConnection, the application closes itself without showing an exception. It is surrounded with a try...except, but still doesn't show no error message at all. Here's the code I'm using to set the connection:
procedure TfrmServidor.confConnection;
begin
with conMySQL do begin
DriverName := LeXML.Strings[5];
Params.Add('Server=' + LeXML.Strings[3]);
Params.Add('Port=' + LeXML.Strings[4]);
Params.Add('Database=' + LeXML.Strings[0]);
Params.Add('User_Name=' + LeXML.Strings[1]);
Params.Add('Password=' + LeXML.Strings[2]);
ShowMessage(Params.Text);
end;
try
conMySQL.Connected := True;
except
on e : Exception do
ShowMessage(e.Message);
end;
end;
Where LeXML is a function that reads a XML file with the properties and returns the values on a TStringList.
What is it that i'm doing wrong?
The ShowMessage with the Params Text returns the following:
[Window Title]
Servidor
[Content]
DriverID=MySQL
Server=10.1.1.16
Port=3306
Database=treinamentos
User_Name=treinamentos
Password=masterkey
[OK]
Can anyone help?
