I just started having this problem myself. Did a "repair" of Everquest program and reran all EQEmu and P99 "to play" steps to no avail. Problem persists...

As I said in another thread:

I think the login server is either down, frozen or on a repeating loop which would effect both servers.

worked for me.

the trick might be to log right off between tries.
