Thanks guys! I tried everything and still couldn't get it go in. Decided to go back to version 6! Funny part is......that one went in perfectly. I figured I had nothing to lose, so after installing 6, I decided to try and install the 7.8.5.0. It didn't say a word about uninstalling the previous version (6), and made NO mention of Fast CD-Burning not being installed on this computer! It went in perfectly and used my ver 6 serial with no problem at all! I can't believe that. Only problem I have now is that I can not get this thing to data verify after the burn, but I guess that would be another thread. I ran out of my "good" DVD's and bought a pack of Maxell from the drug store. Want to blame it on bad DVD's or something because I have not been able to verify a correct burn on a single one of these Maxell discs. Thank goodness there's only 15 in the pack and I've wasted half of them already!
