Deleted that dll and tried what you said and sure enough it fails on the next in alphabetical order, i have never in all my previous mods added anything other than data and mods zips and they worked , every time i tried to take the server data file as well it trips itself up exactly the same as it is doing now, I use the mod launcher so client is ok, its just this server side and then we can crack on, appreciate your help
