R9 390 Driver problems



So i have a R9 390 build into my PC on to a MSI Z170A Mainboard. I had no Problems with its untill 1 Month ago, when the driver update just wouldn't work, so i deinstalled the drivers and reinstalled it and it worked completely fine. Today i wanted to update the driver again and it didn't worked. So i tried to deinstall and reinstall it once again, but i allways got Error 175 or 173, which says my GPU is either from the R5 series or a non AMD Card.

Allready a big Thank You to any helper!
