CUDA VISUAL PROFILER

I am trying to profile my own executables with the CUDA VISUAL profiler 2.2 on Windows XP. But every time it passes the bound execution time, say 30 seconds. No matter how high I set the time, it is always the case.On the contrary, the examples in the CUDA SDK projects folder are being profiled in no time. I have set the CUDA_PROFILE and CUDA_PROFILE_CSV to 1 in the system’s Environment variables, also I set CUDA_PROFILE 1 in the project properties of projects created by me. Please tell me the exact sequence of steps to follow to Profile the executables using the CUDA Visual Profiler
