I am no longer offering Publish on SmugMug. The New SmugMug required a substantial rewrite, and I simply don't have the time any longer to maintain Publish on SmugMug. I recommend you use Send to SmugMug instead or the web uploader that SmugMug provides.
I'd like to thank the folks that have used Publish on SmugMug over the years! I'm sorry I could not keep it updated, and hope you'll find Send to SmugMug a suitable replacement.
Fixed a bug preventing login to SmugMug
Fixed a bug where previously uploaded photos setting did not work.
Fixed an issue with video uploads not working all the time
