I dont wanna have to delete everything an start over. Anyone got any advice??

The best advise is to hit the report button and ask a mod to move your thread to here...

You may even find your situation in an existing discussion. I wish you well.

How old is your Xbox? I'm just thinking that it could be the xbox that's causing the problem, make sure there's no dust in the back and side fan holes, you can just blow the dust out if you take a deep enough breath, otherwise I'm not sure how to fix, sorry.

Its a new xbox. an i can't find any threads anywhere talking about this particular problem :/

I would advise on using a vacuum as opposed to blowing. You could easily make things worse. Especially if to get dust into places that prevent the machine from reading the disk.

One could even argue that a vacuum could harm as well.

I will move this...

Oh my... you could svck up a vital component or something?
