By the looks of it you have two separate license profiles, one of which is for Version 1 of Jaksta Media Recorder. This is the one that has reached it's activation limit. I have increased this limit in the event that it is the one you want to use for whatever reason.
Your other license is for Version 2 of JMR and still has a number of activations left and should work.
I have emailed you a copy of your V2 license key in case you need it.
