If Windows, it is "fairly" common that a Windows Update will change "just enough" that a graphics adapter driver will become out of date
Right click in any open area of the Windows desktop
Select NVIDIA Control Panel from the popup window
Select SYSTEM INFORMATION at the lower left corner
Driver version should be the 1st line in Details
For Windows, do NOT rely on Windows Update to have current driver information
-you need to go direct to the vendor web site and check updates for yourself

Sorry after restarting my computer windows made some updates and it appears to be working fine

I think its my graphics card, now when I press render it is stuck and the program crashes after I hit cancel
Hey John, it took a while but I figured it out. It was an effect I was using with red giant universe. When I didn't use the the transition everything worked fine. I guess it not compatible with the latest cc update.
I appreciate all the help.
