CUDA Visual Profiler Error

I am running CUDA 1.1 and am running Visual Profiler 2.0 and am getting the following message -

Error -97 in reading profiler output.
Unable to open file.

Can somebody point me me to what the reason for this could be

Thanks

there is a search button on the right top, there have been several threads about this. Also I am not sure 1.1 works together with profiler 2.0 (i did not even know a 2.0 was out)
