Re: CTD w/ GeForce 6 series?
gosh I ought to write up a document and use it to cut and paste this response *grin*
There is a KNOWN conflict between DIRECTX v9 (or whatever the latest version is - I think it is 9xx) and the latest NVIDIA drivers.
MANY of us have been successful in rolling back to an earlier version of the Nvidia drivers (one that does not conflict with DirectX)
It would be well worth it for you to check out this possible fix.
Also, search the apothocary - there are numerous threads there about Nvidia and this issue (as well as other graphics issues that might apply to your situation if the driver rollback does not rectify the problem)
If I can help, send me a PM - Good luck
