Hi Daredevil,
It seems i found the problem now, i made a shortcut of the WolfDED.exe file and i can add lines now. I added everything it says include the +set net_port_extra 27965. I tested the server with the 2.60B client and i could come in with 3.0.0 running. I uninstalled my ET and reinstalled the old 2.55. I see the server on the list. However when i connect i get the following error.
