Theatre Files will not play.

Ever since reach was released for backwards compatibility, I’ve been doing alot of recording for my machinimas on reach and I’ve been enjoying the experience. However, lately I’ve been getting an issue that completely destroys the possibility of me ever using Reach for machinima. Everytime I go to theatre mode to view a recent clip or saved film, I keep getting the error message, “This film is invalid. It may be damaged or from another version of reach” This prevents me form viewing any clip or film in theatre and ruins all the plans I had for Reach. I have tried playing on system link, on my console, offline, solo, with another controller, restarting reach, hard rest my xbox one, go into a game with friends, play in matchmaking, clean the disc, sign into another profile. NOTHING WORKS. If anyone knows a solution or why this is happening, please let me know. And if anyone at xbox or 343 is reading this, please get this fix, I was really looking forward to making videos with reach but now those plans are down the drain.
