Try just going to your update on your start menu and scan for updates when you get there oh I had to download a new update program first but I downloaded sp2 today from update
Just download the network SP2 RC2 version and run it I have
had it installed for about 3 weeks and haven't had any problems
so far. The first link is a deep link to the file it is 264 mb and the
second is the main page.
