I am having the same issues with the trial period message. I too have the key directly from slysoft. Sounds like there is some issues with this "update." I restored to prior version and it works fine.
Yeah, I downloaded 2 older versions and used my same key on both, and they worked fine. I then attempted to update to the new version again, and ended up with the same result. I also think there is something wrong with the program and slysoft will probably have a fix in a few days if there's more of this going on like they usually do.
have not had that trouble with AnyDVD, but I did have the exact same issue with my security software (zonelabs). I had to delete it in the registry and reinstall it. Fixed the problem.
