Hello. Where di you get the key from. If you got it off ebay or someplace other than the slysoft site. It may be used by more than one person. When that happens, AnyDVD makes that key invalid. If you really did buy it off slysoft then hopefully you kept your original email. Because AnyDVD will reissue you a key IF you have the original email. I know because I too had my key disabled and I did not have my original email. (Upgraded computers)
