I Need Assistance! (can't save preferences)

[iMunch]

i can't save my preferences on my powerbook G4, which is running panther 10.3.9

i set my preferences to my liking, but the settings return to how they were when i first bought the laptop. it is a used powerbook and i am new to macs. it had all of this cool music on itunes and out of nowhere the music disappeared, and all of my music seems to have "vanished" along with it. can anyone help me with setting the preferences to stay, and can anyone help me return my music too.

thanks!

Did you by any chance change the name next to the 'house' icon on the left hand side of the finder window?

Did you change the name of your user account (next to the house icon)?

If so, see this guide with links to Apple's site showing how to recover from it.
