Did a complete reinstall. I traced it down to 1 of 3 things. 1) Bad or corrupted region I had downloaded earlier in the day. 2) Bad combination of plugins although they all seemed to work fine hours before this mess started. 3) Bad or corrupted program files (NAM in particular as it was only one I had installed at the time). After full reinstall of all of the above listed, everything is fine. My only other suggestion is if someone can figure out why changing the "Visual effects" from LOW to anything else causes that problem then we can get closer to fixing it. Let me also say changing from Hardware render to Software render did absolutely nothing. Systems specs as follows: Support request generated by EAsy. Copyright 2002 Electronic Arts.
