GETTING THE PROFILER WORKING

Whenever I run the CUDA profiler I get the following error message;

Error -94 in reading profiler output.
Minimum expected columns (method,gputime,cputime,occupancy) not found in profiler output file.

So I go into options->default view settings and all columns are shown for the summary table, which include the four columns named in the error message, and the time stamp is ticked for the session.

Is there anything else I need to do?
