Lightroom Export doesn't work -- doesn't do anything at all
I got a new PC and installed CC and Lightroom, imported some new NEFs and edited them. The "export" menu option is available when I select one or more images but clicking it does nothing. No error, nothing. I've tried uninstalling and reinstalling LR, starting with alt-shift and clearing preferences, running as administrator, and moving the files around to different hard disks before importing. I'd be very grateful for any help!
