iPod Issues?

2 days ago I got this iPod Nano (after a year of being iPod-less) and was so excited. Came home, downloaded i-Fu**ing'-Tunes 7.0.16 or something. And right when I installed it, it kept sending a prompt message indicating that theres a problem with permissions in the registry. I spent good 4 hours trying to just install iTunes :s. Turns out this version is buggy and so many people are experiencing problems/bugs with it. It is common to get a message just like the screen shot below:

Anyway but then I found out this "too technical too risky" solution that sorts the problem out. Whoever finds a difficulty with iTunes, let me know and i'll sort it out hopefully :) :)

Now good nite! Can't open my eyes...
