Wrong section, moved. License questions do not belong in the DVD issues section which is reserved for DISC related issues only. The license you purchase entitles you to free updates for that period of time (unless it's a lifetime one, then it applies to the lifetime of the product/redfox). The OPD only speeds things up when it comes to DVD's, it is NOT required when it comes to dvd's. Dvd decryption is solely done by anydvd itself. New protections require new anydvd versions, whereas new blu-ray protections simply get added to the OPD.
Old slysoft licenses only work up to 7695 which is around the end of february last year. ANY subsequent new release has a high chance of not working or WILL not work with 7695. The 7695 version can probably be found through the forum search. That's what that functions exists for.
