NV_Error: Cuda profiler initialization failed

I see this error on WinXP 32, since I updated to CUDA 2.3

‘NV_Error: Cuda profiler initialization failed’

The error appears when you run any program under the profiler. This is with programs that were being profiled without a problem with CUDA 2.2 before the upgrade. Anyone else with a similar problem? Are there any workarounds?

I have tried various combinations of performance counters without much luck.
