Have you recently removed any audio programs? Maybe some of your defaults were reset. Whatever you do, don't convert all of your mp3s to .wavs .. wavs take up a lot more space.
One other thing you might try since you are using adaptec is the "Direct CD" software. I am fairly certain that you can drag and drop music files and have a playable cd. By running this program, you format the cd so that you can drag (or copy) files from one location (go to my computer and open a window and go to the folder that has your music in it) and put them on the cd in the cd rw drive (by opening a second window, clicking on my computer and then the drive letter of your cd-rw (most often "E").
My best advice is not to convert all of your mp3s to wavs. Before you do that you could install another cd creator and uninstall adaptec and see if that corrects everything
