I recently replaced the PC that Retrospect 7 was running on. After installing Retrospect on the new machine, I can't get it to recognize the DVDs I'm trying to back up to. Backups all fail. When I try to validate my script and click Check Media, I get Media for script Nightly Backup unavailable. Writing to any disc that is erased or named "1-DVD Backup Set" I've tried this with a brand new disk, and then I tried formatting it with the name given: 1-DVD Backup Set but I get the same result each time. Retrospect Professional 7.0.265 Retrospect Update 18.104.22.168 Thanks for any help.
