Hello there,
I might have found a way easier solution. Upon purchasing a Vive I experienced the same problem with the same games but thought of this solution as a last resort as I did not want to uninstall and reinstall so many games. I found the whole "international character" thing to be rather interesting, though, and so kept it in mind as I researched further for a solution. By mere coincidence, I happened to discover that under the "users" folder on my pc there were two user folders both with my name but with a slight difference: The international character in one of them had been replaced by a strange character instead. Upon further inspection of the two folders, I found that the folder "openvr" could be found in the folder with the normal name but was missing in the other. I simply copied (not moving) the folder "openvr" into the folder with the strange character. After booting up a couple of games that I had experienced problems with I found it to be all fixed! I hope this will come in handy for anyone who might be unfortunate enough to come across the same issue.
