I've just the other day downloaded the MakeMkv and installed it and tested it on a couple of ISO files to strip out unwanted titles and subtitles etc.
Came home this evening and tried to open the app and I received the following popup

"This application version is too old. Please download tghe latest version at http://makemkv.com or enter a registration key to continue the current version"

I have un-installed it and downloaded the latest version(1.8.3) and it's still popping up and I can 't run it.
Does anyone have any info?

Take a look at this thread.

Not really sure what's causing this but is the key already set here?

The version of MakeMKV that is current is 1.8.3. A new key for this version, which is valid through the end of July, can be found here: http://makemkv.com/forum2/viewtopic.php?f=5&t=1053

Mike usually replaces the current version with an update prior to the expiration of a key, but sometimes doesn't make it... which is why that link will always have the most recent key in it.
