I'm just getting this under Cuda tab:- 2013-06-10 21:33:00: Running command: E:\download\software\Bit Coin\guiminer\miners\puddinpop\rpcminer-cuda.exe -user=****.worker1 -password=**** -url=http://api.bitcoin.cz:8332  Nothing happens and the start button doesn't have time to change to stop, running nVidia International driver 296.10 if that makes any difference?

If I try and run the regular CPU miner I get this:-

I just installed the Cuda pack from nVidia, whatever good that did.
