Hello,
The first thing you need to do is identify the reason why your listing failed (the api error.) These errors can be found by either clicking on the red notification box (at the top of any page of your auctiva.com account) or view your Scheduled listings page--there will be a message in red as to why your listing didn't post.
Once you know why it didn't post, you can go to your Saved Listing and fix the problem(s).
I did look at some of your recently scheduled listings that had error messages, and the reason why they didn't post was because they were from your Closed Listings that were over 90 days old (many were last posted in March of '09.) EBay doesn't keep the original listings' information for more than a few months, and therefore can't be relisted (even through Auctiva.) You will need to post it again from your Saved Listings or create a new listing.
If for some reason you have deleted the original Saved Listing, you may be able to recover the original item description you had in the listing, so you won't be starting over entirely from scratch. It's easier if you can have two browser windows open during this process, so you can have your closed listing in one, and a new listing in the other:
Go to the Closed Listing page and click on the "Edit and Relist" link next to the listing you were wanting to post to eBay. This will bring up the one-page lister with the original information for that listing. You can then copy the information you had in the Item Description and paste it into the new listing.
I hope this information is helpful!
