i have cs4 and rush hour installed, plus nam, the newest version. i planned my city well, and it was well laid out. when i had the money, i added normal rail. my problem was: with added rail, the rail/road crossings didn't work. i tried monorail and - monorail/avenue crossings didn't work. neither road nor rail traffic is possible. could someone please help me? (specs are: win xp pentium 4 2.66 ghz 2gb ram geforce 68xx) i'm sorry if this question has been asked before, but it seems that i am too stupid to use the search function. so if you need to flame about my disability to use said search engine, add a helpful link. thanks in advance, missu
