My fileshare doesn't work. Please fix

My fileshare does not work. It says " The name of the creator of this file is not allowed on xbox live." It’s been doing this to me on Reach and H4 ever since 343 took over. I really want to be able to use my fileshare again, for I have many clips I wish to upload, and I want the achievement that requires the use of my fileshare. Please help me. GT = a Criminai
