Lightroom 6.8 and auto-import
I set up auto-import today for the first time in LR 6.7 and it worked fine as advertised. Shut down and installed the new update. Re-opened the program later and auto-import no longer works. File / auto-import / settings repeatedly gives: 'Unexpected error performing command: ?:attempt to index a nil value'. This bug is not cured by PC (Win 7) shut-down / reboot. Is it to do with the 6.8 upgrade? Advice please.
Thanks,
Eric
