I just installed a few maps (sunday morning, halloween, etc) and now RR hangs, any clue why this is happening?
EDIT: So it goes through to the loading screen and it just goes black.
when you say, "goes black," do you mean the loading screen or it loads a black map? My initial suspection would be that something wasn't installed correctly and perhaps to check your logs to see if anything was reported. My other suspection would be that something is corrupting the game and to slowly, one by one, remove the new maps so that you can pinpoint the problem.
I did exactly that and I found out it is most of Cmdrkoenig67, Humanton's, and the maps from here: http://geography.freedomu.info/
