Getting rid of displayNotification in Delphi 2010

Oooops, I ran into this exception once again, last time it worked fine after deleting the cache files of IE, but it did not work this time. It displayed TEmbarcadero.Create on the upper right corner of the IDE, it seemed attempt on getting connected to the homepage of Embarcadero or somewhere, after several attempts, it failed to load the IDE and said displayNotification堆栈溢出 and out of memory.

So I got into the registry to see what I could do, after deleting all the subitems in the  following items
       HKEY_CURRENT_USER\Software\CodeGear\BDS\7.0\Closed Files
       HKEY_CURRENT_USER\Software\CodeGear\BDS\7.0\Closed Projects

and, it is fine now.
