I too am having the same issue as OP. I tried uninstalling and reinstalling it, same issue. Windows 7 x64
I threw my copy to a clean virtual machine running windows 7 x64 and get the exact same error so I know it's not my computer.
Any other information I can supply, I'd be happy to help.
*Edit* If I'm reading this right, What are the odds the OP and I joined the forums just minutes apart, almost 5 years ago.
