The challenge is that the problem probably doesn't lie with Adobe (who is unlikely to fix an older version of the program regardless). The problem lies with sites like YouTube who are always switching around the protocol so that programs that used to be able to interface with their site no longer can. (I assume you've tried going to the program's preferences and updating the web services.)
Meantime, the easiest solution is to simply output your video using Publish & Share/Computer/AVCHD with the YouTube HD preset. This will produce a quality MP4 that you can then upload to Vimeo, YouTube or Facebook through your web browser.
Actually Steve, I believe it does. When Adobe chat reps can't even be bothered to look into the issue after wasting 10 mins of my time because I bought 13 instead of 14 and now have need of the publish to social media function... it is Adobe's problem. It's also their problem that the program crashes without returning you to your point in the workflow.
Yes I've updated web services - thank you for suggesting.
It is an issue with Premiere Elements, Elements Organiser has no issues with uploading photos.
I appreciate your work around but it is just that, a work around and not a solution. The solution is Adobe bothering to find out what the issue is and provide a fix, that's why they get paid the big bucks. So I've paid for a function I can't use. Unfortunately, methinks The Brick Wall looms large ahead...
In any case, Steve, thanks for your response.
