I have tried to remove and re-install MakeMKV and the latest updates but without any success and keep getting the following message. Could you please tell me how this is corrected?

'This application version is too old. Please download the latest version at / or enter a registration key to continue using the current version.

Pick up the new beta key here: http://makemkv.com/forum2/viewtopic.php?f=5&t=1053

Copy it into your clipboard.

Set your system date back to 11/25. Start MakeMKV. You can set your system date to today after it starts.

Go to Help->Register, and paste the new key in.

Permanent fix is buying a key.

OK great thanks I'll try that, but I'm not tech savvy so bear with me.

How / where can I buy a key from?

'Help > Purchase' from the app menu takes you here:
