When I did tests on LMDE1 several months ago, I couldn't get MC20 running successfully - it does work beautifully in LMDE2. For anyone else using LMDE1 you might want to try the test build found in
this topic but since it seems like you've got the main program running we'll continue to your issue.
Thanks mwillems. I've done just as you suggested. Command Line then displayed a notification which I didn't understand but which contained phrases such as 'not found'. I remembered that the license key expires after fourteen days, so I went on to the jriver site and did what was necessary to get another one. Then repeated the whole performance. This time something was going on, because I got no error messages, but after a few seconds a '>' symbol appeared at the terminal. I tried the jriver icon on by bar and just got the trial version which tells me it has expired. Although at the time I paid for it I followed the steps to install the paid-for version I don't seem to have a separate icon for this. Is it even installed?
Okay, do you have the .mjr file? If so, just type in the following;
mediacenter20 /RestoreFromFile
And put a space after /RestoreFromFile then drag the .mjr file into the Terminal, and press Enter. It *should* license MC20 correctly then - if not, please post the exact error(s) if any appear in the Terminal. If it doesn't work, it might be
missing the correct path to the CA files which is needed for MC to connect to the license server... but we need to know the exact error(s) first, if any occur.
Also, to run MC20 just type the following into the Terminal;
mediacenter20
If any errors appear in the Terminal when running MC20, please post them. If there's errors when running mediacenter20, you might want to try installing the test build linked in the topic found
here.
Now, as an absolute last resort, you can try enabling the
copy and paste buffers and copying your license into MC20 itself when it prompts for it.
