I recently got the vive and after installing the software that comes with it, both DX9 and DX11 version of the game crash. I've tried reinstalling and tried deleting settings to use default but nothing works.

If I use system restore to go back to just before installing the vive software it works again.

980Ti latest driver
Windows 10
