UPDATE I just realized that obviously the free AND the pro version need to be installed.  Now the menu point appears again. BUT I somehow can't activate the pro version - clicking on "activate your license" brings me back on the same page...
I opened a new ticket and this can be closed.

Hi
I installed the free version of your mp3 player. After some days I bought today the pro version, installed it. Obviously it does not upgrade the existing free version so I deinstalled the free version. But now the menu does not include the mp3 player button anymore...??? I deinstalled also the pro version and installed it newly. Still no mp3 player menu point.

Thanks for your support

Joe
