ITunes will not sync to ipod - no error msgs / new laptop

Question

I have a new laptop and have just downloaded itunes and connected my ipod. First, after the download, I get a message that 110 of my songs can not be loaded onto my computer as they are not authroized to play o this computer. I review the songs listed in the message and say OK.
I purchased a song, resorted a playlist, and clicked sync.
When sync was complete, all of the music and files were wiped clean off of my ipod. And syncing does nothing.
My library in Itunes is in tact and everything appears to be fine. I authorized the new laptop on my account and tried again. Still nothing.
I have checked all of the sync settings on the device. I have tried to sync individual playlists. I have played music directly from itunes to make sure no error messages would appear.
Mystery. Can someone please help me understand where I am going wrong?
THANK YOU!

Heya. It sounds like you may have multiple iTunes accounts, and not all the songs were authorized for each account when you transferred things over to your new laptop.
To figure out which account you used to purchase a particular item, follow these steps:
1) Control-click (or right-click) the item in your iTunes Library.
2) Choose Get Info from the menu that appears.
3) Click the Summary tab.
Also note that when an account name is edited, the items purchased before the transition occurred will still list the original account name, but will need the new account name and password to be entered in order for the purchases to be authorized to play.
Once you've confirmed the authorizations, you should be able to sync things fine to your iPod.
Let me know how this works out =)
