TheWiggian: Since i've started to play the witcher 3 or better said my first game on gog galaxy i've run into multiple problems, bugs et cetera. Though 1 or 2 bugs i was able to get rid off since the last update i can't run the witcher 3 over my steam client because it keeps crashing whenever the game starts (i use the steam client to take screenshots).

Now to make it more stable i run the witcher3.exe as administrator and over steam but now theres no steam overlay and i can't take any screenshots anymore.

1. Problem is the steam overlay doesn't work when i run the game as administrator and without running it as administrator the game does crash immediately.

2. Problem is that since i run the game as administrator it shows me the following error twice in a row before the game starts: please check the attachment below.

Translated it's like:

witcher3.exe - No Medium
There is no medium in the device. Please insert a medium into the device \Device\Harddisk2\DR2.

3. Problem is that the game always starts in borderless window.

Anyone got a solution for these problems?
Greetings
