Asset Store crashes when trying to import Asset after downloading

Ok i have the newest Unity just downloaded and install 3.3 and it happened when i had 3.2 too I'm new to this, but ok it downloads

and says decompressing package

then it says:

fatal error! unable o open database fiel UnityEditor.AssetStoreContext:OpenPackage(String,String)

HELP!!!! what does this mean i hit quit and unity closes out Aka "crash"

Ok I Uninstalled and resintalled Unity 3.3 downloading a whole new installer (not sure if that was an issue but did it anyway) I went into preferences and under the general tab i unchecked compress assets while importing and it all works now
