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.
i figured out how to fix this. (it works for me at least) i just uninstalled interstate and reinstalled 1.8 and didnt get anymore patches. then reinstalled the levels. now it works!
