NIS 2011

Hello all.  I just upgraded to NIS 2011, installing via the upgrade link, over NIS 2010.  A couple of issues.  1)  Every time I click on the "application ratings" link on the start screen,  the application ratings page comes up and then freezes.  I have to close the page using task manager.  2)  My internet connection seems to have slowed down a fair amount.  Any help or suggestions would be greatly appreciated.
