Hickory: I run ToEE Co8 on Windows 7 64bit and latest (337.88) nVidia drivers, so that's not the issue. Do you have Java installed, and did you follow the installation intructions for the GOG version precisely (no patches etc.)?
Glad to hear that can't be the issue, as that would have been a pain to get around.
The only instructions I followed were:
Step 1: Install GOG version
Step 2: Install Co8 (nothing else)
Step 3: Run Co8 8.0.1 Patch
And that's it. Also I just double checked on Java but it looks like it's installed.
Edit: Okay, before I posted this I figured I'd try a full reinstall (plus gives me a good chance to make sure it's working before I do any patching, see if that was the issue) and it seems to be running fine.
I don't know how, but I think my CFG somehow got messed up during install, as when I edited it this time it looked totally different.
Anyway, thanks for the help, seems to be working now.
Update: And with the Co8 installed it's running all good. Still a little crash prone, but nothing repeatable. I have no idea what went wrong but glad to see one of the more simple solutions solved it.
