Sudden Static in previously great recorded tracks

Can anyone help? I have spent several months recording tracks using Audacity, and I was very pleased with the results. Suddenly I tried replaying the tracks today and they are full of static. I’ve never had this issue before and it doesn’t seem to be going away on its own. I tried looking this issue up elsewhere, and have not found anything on the subject. I am hoping it’s the working system, i.e. Audacity, and that my files are fine, and that I might just have to download Audacity all over again, and then replace my files on this new version. Any assistance will be greatly appreciated.

WAV files or Audacity Projects ( AUP & _DATA folders)?


Also tell us what version of Audacity and Windows this happened on (see the pink panel at the top of the page).
