Same Problem here. In February, CoH Trial worked well with a GeForce 7950GT, but now CoH isn't working with a GeForce GTS250. Same two errors as above.
CoHHelper shows the following things (although i had an error which says that there is no registry info for CoH):

The only thing i wonder about is the language of the driver. My system is german, the driver is english but did this count as an error?
Ok, so i wiped my old driver (257.something) and looked after driver survivors with Driver Sweeper. Driover Sweeper suggests to restart in safe mode but i can't because i have no access to safe mode at start because keyboard is not reacting (stupid logitech bluetooth thing). No idea how to actvate save mode, so i tried in normal mode...looking for old drivers alsd cleaning all.
I wondered, that Driver Sweeper fund ATI drivers. I never had an ATI Graphic Card in this PC, only a GeForce 7950 and now a GTS250. So no idea where the problem is. Just wanted to delete the ati thingies, but they are stlll there. And hey...they have been there before, when CoH did run well with a 7950GT.
To end this: Driver Sweeper didn't help, CoHHelper says nothing. CoH says my Graphic Card odr Driver sucks. i payed 29€ for CoH and can't play it now. All hail to ne ncsoft support which didn't react...they have no idea how support is working^^
Someone an idea what to do?
