Hi, I also have a registration key issue. I have been able to download the install key, but Media Jukebox still gives the same error:
"Error installing Media Jukebox license:
Failed extracting license from file."
I have the software installed on this computer, and only this computer. Since I bought the full version last year (v. 8.0.289), I have had to refresh the registration key at least 8 times! I do not have a trial version, but that's the initial message I get every time I try to rip. None of my keys worked this time, and I followed the link to the restore page. I also asked for an e-mail version, which I received. I've double-clicked the files, I've gone into the program and chosen the "restore license" option - all to no avail.
One of the [many] times I tried this I got the same "Error installing..." message followed by "OK" on the second line, but still no ripping.
HELP! ?
