When I bought my copy of JRiver Media Server 23 for Mac, I installed it on my home office Mac with the idea of using it with my copy of Logitech Media server to work with my Logitech Squeezebox Touch to stream my audio media from my home office Mac to my stereo system in my living room. Of course that doesn't work (dumb me). What I should have done is install my Media Center 23 on my my MacBook Pro which is connected via USB to my stereo's DAC. That makes a lot more sense. Now, I haven't tried it, but I suspect that once I've installed the Media Center on one Mac in my house, I can't install it on another, but I'm hoping that I can unregister the software on my home Office Mac and re-register it on my MacBook Pro. Is that possible and can you help me with that? I'm retired, on a fixed income, and really can't afford to buy JRiver Media Center again. Thanks in advance for any assistance that you can provide. ?
