Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Make sure you downloaded the Interstate 1.8 Server Files, extracted the Interstate folder to desktop. Copied it. Pasted it into the server's Mod folder and clicked yes to replace everything. Then shutdown the server. Open server manager, check one of the new maps, set it as the new next map. Click start to start the server and see what happens. If not, try reinstalling your 1.8 Server Files. Could be corrupt.
