Since photoshop.com was first introduced in Photoshop Elements 7 and Premiere Elements 7, it has always had the video limitation, that is, you could store, share photos with family and friends, but the system offered only storage for video and no sharing of the video.
But, now I see that is has added the video sharing to the photoshop.com offerings.
What was the size and the format of the video that you intended to share? Did any of your video specification exceed the photoshop.com criteria for your account (free vs plus (paid version)? Have you tried again with a different video format or size?
I have not used photoshop.com for storage or sharing, so I do not know if it really followed through on that August 22, 2009 announcement about starting to offer video as well as photo sharing. I will see whatelse I can find out and report back. But, for now, check out the details of those uploads and attempted sharing.
The Photoshop.com FAQs say that, although you can post AVIs, Quicktime, Windows Media and MPEGs to the site.However, a red indicator seems to be a flag that the materials may be copyrighted. (Apparently, Adobe's standards are much higher than YouTube's.) Could that be the case here?
There are also file size limitations but, if you're posting WMVs, it's not likely you're reaching those.
Here are more FAQs about video on the site:
Welcome to the forum.
ATR has addressed some aspects of the Adobe on-line storage and sharing.
As an alternate plan, you might want to look into Muvipix, as there are "Galleries," that can be shared. This is a "sister" site to this one, and is also great for many reasons. Might be worth the look.
From PE 7, did you send an e-mail to the people you wanted to share the video to? The error message you've mentioned, do you see it inside PE 7?
