It never seems to open for me any more...

well, first off this is the first time this has happened, I connect to hamachi, and then i click on start.bat the game opens but is black for one ssecond and then it closes and goes bak to my desktop... i kno its not a server chek cuz my other computer seems to run it just fine...
