Just found this forum, story is the same -- crashed while streaming video from an unfamiliar website, couldn't boot past the recovery options which identified corrupt ci.dll file. Tried several restore points, no luck. Used command prompt to find and copy to USB some of my files, but not all of them -- couldn't get to my desktop files at all, command prompt wouldn't recognize the path, even though I could see the correct directory -- still don't know why. Booted from and ran an AVG live CD, found nothing, but I still suspect a virus (have been running MS Security Essentials only). . .finally had to download Linux Ubuntu Live CD, boot from it, find my important files and copy them to USB drive. Now, after countless attempts to recover, I'm formatting and starting over. At least I got my files, though, and managed to use Ubuntu without a problem, even though I'm not much of a techie -- it was easier than I thought it would be. Having two computers sure helped.
