None of them,i was thinking also because I didn't add the album and I create an album and I try to add the video and also didn't work.

If I put the link here,it work. This is not the video what I want to post it, it's just an exemple

I'm sorry the site has been giving you so much trouble, and that I can't think of any solutions. I always liked the website, but the various glitches can be so frustrating. I wish there was still someone to contact about these kinds of things. 

As a last resort, I would be happy to post the video for you if you're ok with that (though unfortunately you won't get the Jpops). Hopefully the problem will fix itself somehow though. Best of luck!
