Hi I'm using Windows 7 RC1. I started the demo, clicked the launch the demo button from the Telltale launcher, and then the screen goes blank. Other people had posted that it takes 3 to 4 minutes to come back, so I left it while doing some other stuff. I continued to watch it for 3, 5, 10, 20, after 30 minutes I thought it was ridiculous and tried to quit by using CTRL+ALT+Delete. Nothing happened. ALT-TAB and CTRL+ESC also did nothing. I noticed the Caps Lock, Numlock, and Scroll Lock lights wouldn't turn on or off. So I rebooted.
-Uninstalled, manually removed all registry entries left in the registry.
-Deleted all files in the windows Temp folder.
-Reinstalled from freshly downloaded file.
-Put compatibility settings on for the exe. Tried Vista, Vista SP1, XP Service Pack 2.
