Ok so im having some issues with my computer and its not looking good.. I really dont know what happened, but the default user account that I have been using to log on to my computer has changed to Account Unknown, and now I cant log on my computer using that account at ALL. This is my home computer too and its not on any huge network or anything. All my files ect are on that account and its getting really frustruating.. Does anyone know how to fix this?
