My itunes will not open on my windows 2000

Question

I just got my first ipod its a 2nd generation nano, I went to support to learn what all i neded to do to get music on it. Apple support told me to dl the latest version of itunes so i did that. After I installed it, I went to the icon and clicked it and it would not open. I tried opening it all other ways you can on a comp and all i get is a little hour glass that stays on for 3 seconds and then goes away nothing loads.
I have never had itunes on this comp ever soit couldn't be a matter of having other traces of itunes conflicting with the new version.
I did a complete uninstall and then went through all the steps to make sure there was nothing left of itunes on my comp then i put itunes 6 on my comp and it worked fine but when i plugged my nano into my comp it told me i needed itunes version7 or higher .
I am truly at a frustrated loss and any help would be greatly appreciated , I have a brand new ipod tha ti cannot use and i have been dying to have some music to listen to while at the gym.
