Ok, so I was installing Norton 360 on my computer. I had uninstalled AVG before and restarted my computer. Then when I started to install Norton it said it was uninstalling and needed to be restarted. I did that and now I can't play my Sims games, Wizard 101, etc on my computer. Also says that I have no d:/ drive and I have no idea how to fix it. I tried re-starting and then installing Norton 360 again, but no luck. Then tried System Restore but everytime I picked a Restore point it just accepted and did nothing. When I try restore from disk I get this message: '::{26EE0668-A00A-44D7-9371-BEBO6CA8683}.
I tried to do fix it, but well I got this that it can't fix it and then this: C:/USERS/MYNAME/DOWNLOAD/Microsoftfixit.maintenance.RNP.13626146595533533.2.1.Run.exe
Can somebody please help me? I really wanna be able to play my game when it comes out. Even Winrar isn't showing up. They're just little icons like on a style sheet or something. I've never had this happen to me before. I really don't wanna take it to get it fixed, I wanna try everything else first. Any help would be greatly appreciated. 
I'll love you forever!
