Why do I get an error message when I access my Shopping Cart?

Question

I have no problem accessing Music Store or adding songs to my cart, but I get an error message when I attempt to access my Shopping Cart. My Keychains are in order and my account is active. I have not changed ISP nor is my computer new to iTunes and the Music Store. Suggestions?!
iMac   Mac OS X (10.4.5)

At last a solution.
But, you must be willing to forfit your shopping cart list and start over. If you mangaed to have a hard copy of it printed out before you lost contact with it you are lucky. I was not. But at this rate I was willing to clear out my cart just to be able to start over. (I was using my shopping cart as a wish list and I think it got to be rather large and larger and larger- and when I did try to buy things it took a long time for it to reset itself until I could not access it at all)
Turns out I exlpained what happened to the music store on the link below (scroll to bottom of link page for the email option to customer service)-

-and told them I was willing to clear it out- which they did and they said it was necessary in order to reset my cart. They also refered me to this other link on how to create a wish list in the MUSIC STORE . This was helpful.

IF YOU DO NOT WANT TO LOOSE YOUR SHOPPING CART LIST, I did read that one could try to de-authorize and then reauthorize your computer. At least so you could print out your cart list if it is really long. I did not try this, but it was next on my list of options.
Hope this helps.
