MyMathLab Gripes

So, I’m taking a math course at my school that’s online (I tend to prefer online classes) so we’re doing most of our homework and quizzes through MyMathLab. There’s an exam due very soon also. However, the practice tests are glitchy and when I finally got to the end of one to submit it, it decided to just load indefinitely. I gave it a while (about 45 minutes) before trying to refresh it. Well, apparently that was a mistake. Now it claims I started it and never finished it, has locked me out of doing any homeworks or practice tests, and I can’t even review old submissions anymore. Anyone had this before, and if so, is there a way to fix it?
