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.
Can you try a fresh install of bf... ? Strange that you are having this prob... If it fails on fresh install then that is weird. One thing I can think of is the audio settings in game. Check if they are set to high. Don't see why that would cause a crash but I did setup the mod to use high ideally... (even the worst pc can run high these days I think)
Hmm, even though you set up a separate mod, both map versions crash, with all settings on high. And the crash happens right when the map starts to load.
