We are sorry to hear you lost that auction. I reviewed your account and at the time the auction ended it appears your password was incorrect (did not match between our site and ebay). It appears about an hour after it ended your password was updated on ebay which likely resolved the issue. Unfortunately that was too late for us to win for you. We need to do a better job of messaging when credentials don't match, we are actively working to improve in this area.
If you are still experiencing issues please let us know and we will investigate further.
