Can't pause/access in game GUI
It's very simple, when I hit escape absolutely nothing happens. The game just keeps playing and I can't access the pause menu. All other keybindings work fine, I can fire, enter and exit the Mako, use the space button for the tactical pause, but I can't get into the pause menu. I hadn't played ME1 in a long time, and when I loaded it I couldn't get pause to work.
I tried:
1- Verifying the BIOInput.INI ( %SystemDrive%\Users\%Username%\Documents\BioWare\Mass Effect\Config) file correctly mapped Escape to InGameGUI
2- Restoring a backed up version of BIOInput I had from the first time I activated the console
3- Deleting BIOInput and ran the game so the game re-wrote the file from the DefaultInput.INI file located here: C:\Program Files (x86)\Steam\steamapps\common\Mass Effect\BioGame\Config
4- Verified local files using Steam
5- Uninstalled the game, deleted the Bioware\Mass Effect folder from Documents, and re-installed the game
EDIT: Also, the problem occurred in BOTH full screen and windowed mode. I am running dual monitors.
None of those solutions fixed the problem, making the game unplayable. I have played this game for hundreds of hours on this system, I'd like to play it again.

Please preform a clean boot and test the Game in clean boot mode.
