I found the solution! If you read the small print on the recovery disk instructions, you are supposed to back up your data on a CD or DVD. I didn't read this and backed mine up on an external hard drive. Bad move. I wasn't able to restore my files.
Now I have the fix. First, copy EACH of the files onto its own DVD. (don't try to fit 2 onto a DL dvd--it won't work--I tried that). Copying these huge backup files (~3.5GB each)is very time-consuming, but it's the only way to get your files restored. So now you have one disk for each of the files in your backup folder (I had nine disks-my files ranged from backup.001.fbw to .009)
Next, reboot your computer in Safe Mode (continually click on the f8 key until the menu appears so you can make that selection as your computer is rebooting). Once Windows has started in Safe Mode, put in the DVD containing the first file--the one called backup.001.exe. Open "my computer" and double click on the file to start it. The recovery manager panel appears, and your DVD is ejected. You're then asked to put in your last disk. (mine was backup.009.fbw. Yours may be different.) The "NEXT" button on the recovery manager panel will activate. Click it, and you're on your way! You'll be prompted for each of your disks in descending order.
I spent about 6 hours total with HP support, and no one was able to help me. I figured this out on my own, I hope it works for you!
