Yes I have updated and yes I have quit the program and started it again and yes I have rebooted my Mac.
Can you attach you log files for us? Also, do you have the ability to use the video as a local file today? If so, try uploading it with that option. What size is the video?
Ben, hey I do a LOT of videos and use the 'use local only' option when selecting the video, becuase my videos are large. Can you take one video you're trying to upload - select this option and see if it will work then?
Also, what is the size of this video file?

Err wow, I guess I should have read Matthew's post first.
