I get the same error as well with PT 10 HD2 system. Running Win 7 64bit.

I have had to revert back to 9.0 as I could find no solution. Would love to know if you get a better response.

Someone had mentioned disconnecting from their domain would make it work. I am unable to try that currently since I need to get our IT dept involved and that's scheduled for next week. The new PT 10 disk cache feature that lets you use network drives does seems to be the issue... ;/
