Your subject title said Desktop Explorer problems and Restore limitations. But then in the main part of your post you say you have an audio problem.

Which is it?

What has been complained before?

You said you are not one for procrastination, so you would have backed up your files. 'Would have' suggests you didn't. Isn't that procrastination?

That audio problem. What is the problem? What do you mean by backing it up, backing the audio problem up?

Perhaps a plain description of your system, (required), and a simple description of the problem would be best.
