I did the update to Windows 8.1 last night.
Now if I start up any of the episodes I get what looks like the old Red Blue 3D vision color split and what I assume is an error from my video card overlaid on the screen that says the game is rendered at the wrong depth.
I checked to make sure I had the latest drivers for my video card. It's an Nvidia GeForce GTX 680. It was working fine a few hours before I did the windows update.
Anyone else having this problem? or maybe know of a workaround?
