HAD something similar, mine loaded the oculus software but didn't let me log in it just froze after. I fixed it using REVO uninstaller (free version) apparently there's a corrupted trace left in the registry when you uninstall using the normal oculus uninstall (lots of stuff left in your C drive after the uninstall) revo scans it and you delete everything oculus and re install oculus and it worked for me The revo is easy to work with just follow instructions it will give you a similar page like when you go in windows control panel to uninstall a program, click oculus and uninstall in the bar on top. Oculus will uninstall as usual, then revo will scan, show you all that's left and ask you if you want to delete, anyways just follow it's easy, you want to get rid of everything oculus (your games and programs will not be affected)
