I haven't used Vista much but I know for a fact it's a total pain. But it looks like you do need the SP2 update. Or just upgrade to Windows 7 (100X better than vista). I'm guessing maybe the issue is you don't have Sp1 installed yet? In that case go to http://support.microsoft.com/kb/935791#Download . You need to choose either 32 or 64 bit depending on which version of Vista you have. Then try to install SP2. Good luck!
