I'm aware of that "trick" with evaluation software. (Pushing it forward, then rolling it back) But I never really adjust the clock at all, except for the occassional re-sync with windows.com. Just to be sure this wasn't the problem though, here's what I did.
Actions Taken:
Uninstalled Circuit Design 10.0.1
Synched clock with windows.com
Reinstalled Circuit Design 10.0.1
I still received the same error message.
