F@H problem after swapping ATi to nvidia

[TomO]

swapped out an ATi card for nvidia card in one of my rigs, unistalled ATi drivers, took out card, fitted new card, installed nvidia drivers, so far so good...

have unistalled and reinstalled F@H and get the following error in the log

[14:47:26] Entering M.D.
[14:47:34] CoreStatus = FFFFFFF6 (-10)
[14:47:34] Client-core communications error: ERROR 0xfffffff6
[14:47:34] This is a sign of more serious problems, shutting down.

and the following on screen pop up.

"Folding at home has run into a serious error running the core and will shutdown"

any ideas?

latest nvidia drivers off their website. didnt run driver cleaner. can i run that after the event now?

 

[TomO]

where are these files then? surely they would clear these out on an uninstall?!?
