.enl Libraries not opening - Mojave / EndNote 9.3.1

Help! My library is not opening at all, no window. The library copy isn’t opening either. Tried a ‘recover’ move, now the recovered library won’t open. Tried a new library with online synb, now that won’t open. Tried a new library with imported pdfs from the original data folder, half of them were minus the citation info so lots of work ahead, but now that won’t open.

What kind of bug is this?? Any ideas? The original library seems to still contain all the data (copied into txt file and it was all there) and the data folder has all the pdfs. Word still makes connections and adds citations, I’m just working blind without the library window open.

Thanks for any assistance!
