I have a similar problem to that of mars 2017 (" Can’t work offline with Panorama X
This time, after forcing to quit and then re-launching Panorama, I get the puzzle (“more than 16 hrs” etc… which actually is not the case). Sometimes I cannot re-organize the puzzle (everything is frozen), sometimes I can but “Check network” button won’t work. Instead, it triggers a message : “Resume statement failed (no pause)”
I guess this happens after using a proxy on one session, while Pan X open on another session. Won’t do it again… but how can I fix this. All db unavailable.
