Losing connection between tests

[Vanessa M]

Hi! 

For some reason now Alt Unity Tester is losing connection between tests, any ideia what might be causing this? I can only execute one Testfile at time, if I have to run more tests, I have to stop and restart the application between them, which is very time consuming.

I get the error

ERROR|OneTimeSetUp: System.Exception : Could not create connection to 127.0.0.1:13000
  ----> System.Net.Sockets.SocketException : Connection refused

Ideas?

Many Thanks,

Vanessa
