First off I love using MakeMKV and used it many version. But for some reason i am unable to use the new version. i keep getting this message:
The application version is too old. Please download the latest version at http://ww.makemkv.com/ or enter registration to continue using the current version. Any ideas?

There are a LOT of messages already on the board that have "old version" in their title, with answers to your question.

Most are in the "general" section, such as: viewtopic.php?f=6&t=18173#p66578
