Can't get past the desktop. Window pops up and automatically closes. Tried everything ( Changing resolutions, in game and monitor), doing all the port changes for Eqhost.txt. Running in compat mode for XP SP2, Running in 640 Reso.

Any help would be sweet =/

Whenever i switch to the play in 640xX mode, i get this error.

The instructions at 0x043abf66 referenced memory at 0x0000188. The memory could not be read..

If that helps any of the more computer savvy out there
