Ebay has recently made some changed to the posting process used by 3rd party listing services, such as Auctiva, to make it easier for developers to comply with the European Union restrictions for business sellers. Additional information on this new policy can be found on the following page: http://ebaydeveloper.typepad.com/dev/2008/01/logic-changes-f.html
If your listings fail to post as a result of this error, the exact error message you will see next to your posting failure records on your Auctiva Events and Scheduled Listings pages is as follows: You are unable to list items, because you have not confirmed whether your account is for personal or business use. Go to My eBay -> Personal Information -> Account Type to confirm your account type now so that you can continue to sell
If your listings are failing to post as a result of this error, you just need to go into your eBay preferences and define whether your account is for "personal" or "business" use. Once this change has been made, you should be able to successfully post the listings that were previously rejected due to this error.
