Hi
I'm running XP pro 64 bit with EECH all mods + 1.9 exe. No problems, so it shouldn't be your os that is the trouble. You have applied the offical patches after installing, and let it do the first time graphics conversion?
Also, you could try running it in a window. That setting is in the ini. file. Also, you could try and delete the ini. file EECH will crate a new one at start up. That solves troubles sometimes. Generally, it is a good idea to follow the install instructions by protocol
here.
Cheers Porphy
