Thank you

Try to reboot. And if you want some more productive advice, please, post more info next time.
K Rider:
I have three GTX280's with the V9 multi GPU version installed and it only uses two cards. Is there a setting I need to change or is this a limitation of CUDA/BOINC?
Thanks

I downloaded and installed the AMD version. Running under Windows 7 with a Geforce 9800 GT and I'm getting errors with the multibeam part.
I did back up the complete Boinc data folders and have restored and back running as before and I did reboot before starting the new version.
No doubt I've done something stupid but here is the error log for one failed workunit grabbed from client_state.xml:

COULD be a driver issue. What nVidia driver do you have installed?
