Hi queenofcollectible,
Thanks for posting here to let us know about this. We encountered some technical problems with our posting service in the wake of our site update this morning that caused a number of failed listings in the 9 o'clock (PDT) hour. This issue has since been resolved so you should now be able to post any listings that previously failed due to this issue successfully by trying again.
We apologize for the inconvenience this issue caused. If you need any further assistance with your account, please feel free to contact our customer support team by mousing over the "My Account" tab within your account and selecting the "File Support Case" option.
-Mike
