invalid username for mpgh

im tryin to get the public hack, i got to settings, and when i tried to put in my mpgh user, i did, saved it and when i go to start combat arms, it says invalid user, please register at mpgh.net and edit your settings.ini file using edit text... anyone know what to do or what i can do to fix this? i have a user already it just isnt working.

Yeah I'm having that problem too, I'm guessing its just the validation email I need to accept, but I havent gotten one of those either... Can someone please help?

didnt the pub hack get patched?
