Bigpsycho's fix works!
Here's the fix step-by-step, but BE VERY CAREFUL IF YOU ARE A VIRGIN TO REGISTRY EDIT!!!!
Now find and open "Run" in the start menu, or search and open on the Windows 8 side menu
Type "regedit" into the text box.
Click OK
A window titled "Registry Editor" will open.
Look for "HKEY_CURRENT_USER" in the left column, click on the small triangle to expand it.
Find the folder "Software" underneath, expand it.
Find the folder "TelltaleGames" under that and expand.
Find the folder named "Launcher"
Right click on the folder
Select delete
Now close the "Registry Editor" window and forget it even exists!
Restart game.
