I am exporting from LR using a third party plugin (Friedl) and a window will pop uo saying "Network Error contacting up.zenfolio.com", which has a progress bar and a Cancel button. However, the cancel button does nothing, and with these windows up, LR is completely unusable. The upload still seems to be progressing, as the progress bar top left keeps moving to the right, but I can otherwise do nothing in LR. Since the upload still seems to continue I don't want to force quit, so I am completely stuck! And since this upload is taking hours, I'm stuck all day for sure, and into tomorrow. Any ideas? See the screenshot below of the error box. Thanks!
