Can't post to DTube for 3 days

I just started posting on DTube a week ago with daily uploads and the process was flawless. But started 3 days ago, I get a variety of errors when uploading video files. I've spent hours trying to figure out what to do differently.

I love this platform but this is so frustrating. Here is a screen shot of one of the pages I get stuck at. Even when I get past this page, I get "can't submit to blockchain" message. Any help would be greatly appreciated.
