Kontakt Player 7 Instruments in Demo Mode

plaine

I'm currently using Kontakt Player 7.10.5 and Logic Pro 11.0. When I start a new session and use Kontakt to load Guarneri Violin, it works fine. However, when I open a session that I last saved on March 24th which has that same violin, it tells me that it can't locate the instrument files. I use the finder window to locate the files manually to make the association again, but when it then does into "Demo" mode and the instruments don't work.

The interface also looks like the previous version of Kontakt Player 7. Is this related to upgrading Kontakt Player 7 at some point since March? If so, how might I go back to the March 24th version, whatever version that was at the time? Right now, this old session is totally unusable as I have numerous instances of this instrument (and others) that are going into Demo mode when I reconnect the files in this apparent old version of Kontakt 7 that's loading. Thank you for any help!
