Asset Store Bugs - Unable to update extension and consistent problems!!

I was just trying to update uScript when I encounter this problem. I followed the procedure from uScript developer as stated on their website to delete the old uScript extension in Project menu, go to Asset Store and press update, and I encounter the SAME problem “Already up to date” (since beginning of Asset Store). I force update by choosing “Download Anyway” and now it tells me “You must activate your account”. I have activate my account 3 times through Asset Store email verification system now, and I still can’t update and it still give me the same “Already up to date”, and “You must activate your account” messages. Something is seriously screw up with Unity Asset Store.

EDIT: I have just updated to the latest Unity 3.4.1 from 3.4.0 and still having the same problems.
Unity didn’t fix anything. Its already several versions now (3 versions?) since Asset Store was introduced and I am still having problems with it. I have to force download every single time to update my extensions and now its asking me to activate my account even though I re-activated it 3 times in a roll and it still won’t let me update.

I experienced pretty much the same thing,

clicked link in my email from unity to activate my unity profile account

It’s only after logging off in Unity then quit, re-launched Unity then login did it allow me to purchase then i got my purchased asset. so i assume updating already purchased assets would work that way.

I had the same problem, logging out and back in to the asset store solved it as runner suggests.

Thanks guys, I discovered the same fix as well by logging off and logging back in seems to fix the “You must activate your account” problem.
