Bought the game today and installed it, when i launch it, it opens but then the window goes white with a black border around it, then it crashes. I've tried installing the XNA Framework again but that din't fix it. I really want to play this game so any help would be appreciated. And other GOG games like SOMA work flawlessly so it is just this game.

Here is my crash log as well:

This is happening due to something with the GOG client and how it launches the game, I think. If you go to the installation folder and run the EXE by itself, the game works.

This works! But i won't get the cloud save feature anymore will I?

I hate how I don't get notified for replies. No, you probably won't be able to use the cloud save feature when launching outside the client.

I STILL have not heard back from GOG support. So much for that 12-24 hour reply window.

I have the same issue and just posted my own thread about it.
