Can no longer commit to repository

I have an account that I was using for about a week with no problems checking out or committing from multiple locations. However, I can no longer commit code and get a 400 Bad Request error from ALL locations now. I am using 3.5 MBs out of 10, so I should be fine on space. I have tried checking out the repository to make sure that the location, username, and password are all correct, and it works every time. Anyone else have this problem with commits no longer working??
