SOLVED Unable to launch in VR anymore

I am unable to launch in VR anymore. Works fine with the other SIMs, but when I launch RF2, itt says error in Steam VR and always go back to the first RF2 menu.
Any advice?

 

Have you verified the SteamVR files? Steam Library -> SteamVR/Properties/Local Files/Verify Integrity of Tool Files

 

Thank you Mark, no I have not, Steam VR works fine, it is RF2 that does not want to launch.

 

I would still check. SteamVR may well start, but may not actually start when you launch rF2, particularly as you say it says error in SteamVR. At least you would know that the SteamVR files are OK

 

Welll,well, I did a reboot, tried again, but this time everything worked.
All is well, until next time.
