My old SSD operating system crashed. I replaced with a temporary HD and when I reinstalled a trial version of AnyDVD I was able to easy register it with my saved key with your "Register AnyDVD" app. I just installed a new SSD re-downloaded your most recent version of AnyDVD (8170) but when I tried to use the same key I was told that it failed. Please let me know how to re-register my copy of AnyDVD.
