Hello Oerjan,
Thank you for your question about these 4 items. We investigated what we encountered when we submitted your bids. Each one returned a generic error message from eBay, "Unknown Error." Unfortunately, this is all of the information we have. This error only occurs a few times a year and it probably has something to do with configuration.
Please go to BidSlammer Preferences and take the steps to re-authorize. If you see the error message after that, please follow up with us on this thread.
Thanks, and we will watch for your response.
