I tried to launch the mission that is after the vault this morning for the first time- It said "patching 13 files..." then crashed.

after that, When I log into the launcher, It says "patching" in the lower left hand corner - but even after being left alone for half an hour, has not done a darn thing.

I've tried a force verify, and to launch in safe mode without any luck. I am taking it upon myself to redownload the launcher to see if that will help me any, - open to any other suggestions.
