I would recommend you try listing directly to ebay. That usually gets a very specific error for the generic API you mentioned. I'd list it exactly the same, use the HTML export to move the description and use exactly same Title, etc.
Everyone keeps saying the APIs are a glitch, but they seem to keep hitting some real problem. ebay has really cracked down, so it could be just about anything.
Yes, it could be an Auctiva problem. But, those usually have the Forum flooded with posts.

Edit: Just recalled a new policy that tripped another member a few days back. Seems for International sales on some restricted items, you must have a verified PayPal account and it must be linked to your ebay account. Here's text of messge they got on a direct submit to ebay test:
