Hi Laura,
I see that a listing of yours failed to post and the error message "Not Posted in Time" was returned.
This is a non-specific error message generated in respoonse to a communication error between Auctiva and eBay. You should be able to post this listing again without making any changes.
If you are still unsuccessful, you may want to try generating a new token at Auctiva -> MY Account(tab) -> Ebay Settings -> Get New Token. Once you have done that, you may have a better time posting your listings.
