Can you tell me if GPUMonitor.exe is in the process list? If not, please run it manually from "C:\Users\<username>\AppData\Local\Microsoft\Windows Sidebar\Gadgets\GPUMonitor.gadget\GPUMonitor.exe"? Let me know if that works. The data is written and read using the user's "TEMP" variable. So even if it was not in a normal location, they would both still be using the same location.
