Hey,
After I open the emulator, I get "nullDC_Win32_Release.exe has stopped working"
I had the same error initially with nullDC that I downloaded directly from their site. Use the links in this topic to redownload the client, I played for about an hour last night without any major issues.

I'm running nullDC 1.0.4 8)
