Cuda & caudart

i’m a beginner in Cuda programming. i installed cuda_toolkit_2.3 and cudasdk_2.3 for win32 as mentioned in the installation instructions.
But when i try to compile and run the example of project template, i have the error “access violation …” and when i try to compile step bu step, i have the error “cuda version is not compatible with cudart version”. My cudart.dll is version & and cuti32.dll and cutil32D.dll are version 2.
anyone has any idea ?

ps: i’m using VS 2008 in XP and my card is asus EN9800GT.

What driver version do you have installed?
