Nope, it says:

to get a new licence.
I now see the reason: Some bug in APP 2.5 has made it try to use an older registration code, a version 1 code, instead of the version 2 code which was in use by my copy of APP2. When I enter what I now realize is my proper APP2 code, it works.
Of course the links causing the missing symbol error is another issue.
BTW, is the batch renderer no longer supposed to do a preview as it renders? Also the little pop-up toast over the KDE taskbar when the render finishes displays, but is blank.
