No DRAM reads/writes in visual profiler 3.1.1

I can’t select (or even see) the DRAM read/write profile counters in the visual profiler. When I select ‘Global Memory Throughput’ from the Session tab I get the message ‘Profiler counters ‘gld_32/64/128b’ required for global memory throughput calculations are not available.’ I’m using a s2050 so those profile counters aren’t available to me anyways. It seems like the profiler thinks I’m using a different card to what I have, and gives me the option to select profile counters for neither.

I’m using v3.1.1 of the profiler, 3.1 of the driver and runtime and it’s all running on Scientific Linux v5.2. If anyone has any suggestions they’d be much appreciated.
