Odd! Yeah I assume the engine must have been recompiled to work better with other languages. I unfortuantely don't have any engine souce code (otherwise I'd fix so much more.) So I can't actually fix any of these issues.
Your best bet is to wait for a legal re-release and hope whoever handles that manages to do some engine improvements!
And odd that you're getting windowed mode crashing, because I pretty developed the mod using exclusively windowed mode. This engine is really buggy with certain machines, so it might be related. I'm sorry!
