OK at home I have my media server and my laptop, both have had MJ installed for ages, except that my laptop has always had a beta version that wasn't 100% stable and couldn't seem to automatically update itself. So finally I decide to do something about it, and I manually install the latest 8.387 release over the top of my existing install - worked fine, or so I thought, since today when I try and click on a streaming link on the web, MJ says something about no licence, etc, click OK to restore your licence.
So I click OK, get asked for my registration key, enter it, and then MJ comes up and says "Error installing Media Jukebox license: Failed opening license file." I click OK, then figure I better come here and post about this, since I don't know what to do. Then I realize I better have the exact text of the error, so I hit back in my browser, IE says "page expired", I hit F5, get the same message in MJ again, leave it on-screen, come here to try and post on this forum, can't login, re-register, go to email to get my password, ACK! "You have been charged one restore" TWICE! Okay, I understand how this happened, but it's irritating, especially since the only reason I had to do a restore was because MJ couldn't update itself.
Now I went and checked the FAQ and "charged one restore" sounds a bit scarier than it really is - ten free per year! No problem.
So getting back to the real issue at hand - how do I fix this "failed opening license file" issue? I searched here already, but no mention of it.
