Windows 7 Upgrade Advisor

Am running Vista Premium (pre-installed) on my computer which was
purchased in June 2007. I am now thinking of updating to Windows 7 but
here lies the problem.
Have today downloaded the Windows 7 Update Advisor to check my
computer but when i tried running the programme it came up with the
following message * Windows 7 Update Advisor was unable to reach the
Microsoft server for compatability information. Check your internet
connection and try again later *.
Now i may not be up in the world of computer technology but can
anybody explain why this should happen when i can send this email from
my own pc via the internet?
Would it possibly have anything to do with the fact that the pc keeps
refusing to install 2 updates these being;
1) Service Pack 2 &
2) Net Framework packs 3.5
Also some months ago i lost the * Adjust Time/Date facility * but have
not missed it all that much since it is rarely used.

Any help in resolving these issues would be greatly appreciated.
