I went to turn on JR and saw a screen that prompted me to enter my license key. After doing so, I was able to enter JR and use as expected.
Later , I noticed an email saying that I needed to restore my license, adding that I had nine restores (out of ten per year) left, and something about the restore being temporary for only 14 days.
What is going on? I find this entire experience baffling and frustrating, and I'm not sure exactly what it is that I'm being instructed to do.
The only event that I can think of that might have some bearing on this issue is that I inadvertently deleted my entire library, which included the files previously loaded from an external drive containing the material used for playback via JR. I subsequently reloaded the files, and JR worked as expected for a brief time after.
I'm beginning to wonder if perhaps JR is more trouble than it's worth (the $49.95 or whatever that I paid. I hope not.
