I installed version 23 on my Mac in December and all worked fine. I need this JRiver version because due to hardware problems I'am stick to OSX 10.7.5. Today it stopped working (4 weeks trial I guess).
I purchased a license (assuming that this would permit me to install v23 again) but apparently the key only works for V26 which of course does not run on my machine.
Thanks for your help and advise
