Think there might be a patch issue as of this morning!
 

Hey, don't know if coincidence or not, but here's what happened...

3 days ago, installed and patched EQ on 2 machines...runs fine on 5.6 Server I have up, and anyone elses 5.6 servers..

Installed and patched as of this morning (about an hour ago) on a 3rd machine, and I couldn't log in to any servers. So I did the whole driver thing...etc etc etc. I even rolled back all drivers to where I started. Then I got curious, so I patched again on one of the original machines that worked fine, saw it d/l a new executables...so I copied the execs from the one working machine left to the one I installed today, and BAM, works perfect.....let me know if my machines is just dumb, or I am.

I would say you are....there are already a few posts regarding this recent patch already. Just copy the eqgame.exe from the working system like you did and wait till the Devs here update EQEMu to patch.

BURN!!!!

:P
