Error Message when I try to connect to P99 Server

[Dyack]

Under the Underfoot client I've managed to successfully connect to TGC's server. I installed Titanium so that I could try out the P99 server but I seem to be unable to get past the server select screen.

This is the Error Message I get:
The instruction at 0x004a533e referenced memory at 0xbcdae980. The memory could not be written.

Afterwards on further attempts it would only say that "An unknown error occurred" Any suggestions?
