It's not a lack of support per se.
The forums are basically set up for users to help other users. The official support channel is via email to support or through putting in a support ticket. This even applies to the 'Stardock Support' channel.
However, people from support do frequent the forums when they have time available.
If nobody has responded then it means none of the users have an idea on what to do to help and somebody from support hasn't seen it.
I did find another post where Draginol asked the OP what kind of problems uploading to which a response still has not posted
linkI also saw yours
link but I don't have a clue - I don't have Vists - and I'm assuming you're not on dial up.
I know they set up a test page for uploading - looking for feedback - trying to improve the upload process (not sure they were really ready for the traffic due to the size of dreams) - just checked and saw your reply
I don't know how many people are working there at the moment, but it is the weekend and I think most of them get the weekend off.
Since the test upload page is posted by T-Man and I don't see a recent reply by him then I have to guess he's either off for the weekend or working his ass off trying to get it sorted out and is too busy to reply.
While I understand the frustration and even though I have no reason to download any dreams, I suggest you just hang on for a while - it will get sorted eventually
