Hi Lar,
you say that you get dll errors now since rolling back the application of the latest drivers - have you used system restore to remove the latest drivers?
When applying any patches like this, I use Acronis True Image to take a copy of my pc prior to application, then if problems occur like this, that can be used to remove any traces of the application - saves a ton of time - but thats all very well in hindsight :-(
So, on the drivers prior to the latest, did you set the resolution as suggested, in MC?
