Cant activate MakeMKV

[xwarman]

As I try to start I got an error that I should activate MakeMKV. Afterwards MakeMKV cloeses imediadly.
If I leave open that error window and try to register over program menu, I can enter my key. After that I get another program error. If I click that ok, program tells me to restart to take effect. If I do so, same begins again and in the registration field is preentered: "Freeware" like it was before.

What can I do?

Thanks a lot!

OK certainly seems to be an issue see also 'key not working' http://www.makemkv.com/forum2/viewtopic.php?f=4&t=8768 and possibly this one too http://www.makemkv.com/forum2/viewtopic.php?f=3&t=8631
