Unfortunately I'm having the same issue with the main menu, however I cannot find the following folder:
C:\Users\[your username]\AppData\Roaming\Autodesk\Autodesk Vault Professional 2012\Objects
That will be the folder structure of either Windows Vista or 7 - please note that the folder AppData is hidden, so either you will need to have hidden folders exposed or manually type in the folder name under you User's profile.
I hope that helps.
