Launch the game directly from the .exe in the folder? (and try running .exe as admin)
Run .exe in compatibility mode?
Verified integrity twice. Each time I was required to download 6 files at 2GB and each time it did nothing to help. Launching the .exe gives me the same message, whether I run as admin or not. I've tried running in compatibility mode but still the same message.
