Endnote X7 hangs and now cant be opened at all

I have just installed Endnote X7 on a new Macbook, after managing to salvage a backed up library from my old (dying) Macbook Pro, and I had it all working, pretty much

Tonight I was trying to set up the automatic imports from my pdf folder, and as soon as I did so Endnote froze. Now when I open it I just get the spinning ball, and cant access any of the commands from the menu bar

a) what did I do wrong?

b) what do I do now?

Should I simply delete the program and reinstall? I  cant access the menu to properly uninstall it, and am worried it will create more of a mess if I just try to hunt down all the relevant files and delete them.

Below are the opening details from the diagnostic report:
