Are you talking about logging in to Windows and being put into "Temporary Profile" due to some error? This "Home Audio" forum is not the best place to ask such kind of questions.
But if this is the case - "Temporary" means "Temporary". Once you logged out, that profile is no longer accessible. You could try some fire recovery utility to look for your files, but your chances are slim, and if you don't know what you are doing - stop using that computer and look for professional help.
