I bought PS:T a few months ago and it kept crashing on launch. I tried a few possible solutions but nothing worked, so I left it alone because didn't have the time to delve into it.
Last week, I tried launching just for fun and lo and behold, it worked nicely for no reason at all. So I played until after the Dead Nations thingy and then decided I wanted to try some resolution mods.
Which sure enough killed my game deader than the dead nations. Since I was unable to repair it, I uninstalled the game and reinstalled it today, without mods. I also bought the Enhanced Edition because I thought I might not need the mods after all.

I tried to launch the game via GOG Galaxy, via torment.exe, via launcher.exe, in 640x480 modus, as administrator, in any compatibility modus known to woman, and the result is always the same:

White Screen and a Windows Notification that the game doesn't work anymore. No information beyond that, it just crashes.

So basically, I now have two games that I paid almost 40 Euro for, and BOTH DON'T WORK.

System ist Windows 10, if that helps. I hope someone can help me!
