iPod-iTunes help

I just got a new iPod Nano today for my bday, and im having some trouble with my iTunes.
Everytime i try to open it, it gives me this message:

The folder "iTunes" cannot be found or created, and is required.
The default location for this folder is inside the "My Music" folder.

I checked the My Music folder and the iTunes file is there, i tried reinstalling iTunes 2 times both from my computer, and removing it completely and downloading it from the Apple website.
Still nothing, there are other ways to get music on my iPod on my computer, but those aren't working right either, help me please?

EDIT: I figured out my problem, but now i need to know if i can trst iTunes with my mom's credit card, she's paranoid i have no idea what she's worried about.....

Floola is a light weight, iPod manager. Download and read the instructions and you will be set.

However, its not currently compatible with iTunes 9. It should be in a few days. Why do you try something like songbird?

Use Songbird to transfer your music. Uninstall iTunes as fast as you can and bury it deep. Enjoy your new iPod!
