Adobe Encore is not running

Hi Guys,
I have an AMD Phenom Quad core with a nvidia 9800gtx running on windows & ultimate.
I have been trying to run my Adobe premiere CS5 but I get this error message:
Adobe Premiere Pro.exe – Entry Point Not Found.
The procedure entry point.
?FillWithOpaqueBlack@GF@@YA?AW4cudaError_enum@@AEBV?$shared_ptr@VDevice@GF@@@boost@@PEBXHUPixelFormat@dvd mediatypes@@HH@Z could not be located in the dynamic link library GPUFoundation.ddl.

It had no problems when I installed it.
Thanks.
