Hello, I would like to know if it be possible to use the IP of the master server of the X10 version to free the version P, so yes how to make to change the IP? Thank you

Not sure P has been patched, but this thread could be of interest..

Yes it can be done. No I can't be bothered. The instructions are in the last page of the thread.

Thank you Mister
