stAn99 you have me in skype, please contact me there so that we can discuss your issue :-)
cas, I am sorry, this is strange. This tables are not touched by the updater. EXcept you used one I sent in skype. There was one aio doing bad things. You may post me your table layout here. When there is no data in the table, just delete it,... go in your BE and store your shipment method again, the table will be recreated.
