System rating is not available

This is very, very bizzare. If you run winsat -prepop from an elevated cmd prompt after you clear out the .xml files, does it generate the XML files correctly?

Would it be possible for you to zip up the \DataStore directory and post it/upload it here for review? Something's not right, and I want to rule out the rating files themselves.

Hrm - it seems like the data's all there. I'll have to put these in a VM and sysprep it to see if it works for prepop.
