I tried to burn a CD this morning, and it got all the way to the "finishing" part, and then it wouldn't stop spinning, then it said that the CD could not be completed and that the disc may or may not be usable again. Of course the disc is no longer useable~I tried on another computer and was able to burn with no problem, so it wasn't the program that was burning or what I was trying to burn. I don't know what to do! Please help! Thanks!
