Hello Liquest -
We are not aware of any issues with scheduled listings that would have prevented them from posting, so it is unclear what may have occurred for you. I took a look into your Auctiva account and there were no failure notifications remaining in the account, but if there were API errors relating to your listings the failure notifications would likely have indicated where a difficulty was if you received any.
If you continue to encounter difficulty, please file a support case from under the Help tab of the site letting us know the details of what occurred and if there are any related messages or notifications in your account, please leave them intact so we can look into this further.
