Asset Store in editor broken (still)

I originally posted about this here (at the end of October last year):
http://forum.unity3d.com/threads/148559-Unity-4-Beta-Asset-Store

I’ve also posted Unity editor bug reports about this. Case numbers:
498948 502319 520992

I’ve heard nothing back. I’m very frustrated because I’ve spent a lot of my own money on Unity Pro licenses and on the Asset Store. I’m guessing I’m the only one with this problem.

Up until recently I was only able to search the Asset Store to purchase addons. I installed the newest Unity 4 update 2 days ago, and now I can’t even do that. I get an Unexpected Error everytime.

This is the view I get when I open up the Asset Store:

This is the error I get when I try to search in the search field:

This is the view I get when I click OK on the error box (but I can’t click on anything):

Unitys functionality is very reliant on the Asset Store as it is now nearly the only way to get extensions/plugins etc, and so is severely crippled by it not functioning.

Thanks in advance.

Does it work for you in a normal browser? I.e. does the complete page load and can you search?
