hmmm... yea, maybe you actually deleted some "files"... What are you using ?
When I loaded the Roxio, after installation it went into reboot but it did not reboot. I then followed some path which led me into the back door that allowed me access to the Add/Remove utility and I then deleted the Roxio. That did not help.
As I said, I have a Restore CD that came with the computer but I'm paranoid to run it not knowing what the heck I'm doing........
