cudpp access violation

Accelerated Computing CUDA CUDA Programming and Performance
1

My program is terminating with the following Application Error.

The application failed to initialize properly (0xc0000005). Click on OK to terminate the application.

I think that this has something to do with CUDPP. Any suggestions or thoughts would be appreciated.

the following is my scan.cu file that I am linking to from my main file.
