Can Sign in to Project1999 but not into the game or EQemu

Hopefully you were smart and didn't use the same username and password for all of the various places.

You should have a separate username and password for:
EQEmu site/forums
EQEmu login server (used by P99, this is what you need to login to the game)
P99 site/forums
P99 wiki

Hopefully that will jog your mind in figuring out what you used in each place.
