Clearly Wilco was unable to find your info in the banlist (usually he would've said though, if he wasn't snowed under, which he might be).
Alternatively, maybe he found sound of your ban-info, but not all of it, so there is some part (IP address probably) which is still in the list and causing you to get booted.
Please write the full text of the ban/kick message you are seeing, including any bits you think might be irrelevant, but might help us find you.
Failing that, PM me or Wilco with your Battleye GUID (not the ARMA3 playerid you gave us up top - that is useless for unbanning), and the IP address you're connecting from. That may help pin things down.
