I just bought the game in GOG, but it doesnt start. Play button in the GOG client turns from grey to green again after a few seconds.

Problem seems to be in SupportTool.exe

I can get it to run using the .exe in the game folder but I want to use the cloud saves and achievements. Anyone else having this issue?

Same problem here :(

Same issue, can't start the game through GOG. I have to start the game using the exe. from the bin folder.
