My son has Trainz 12 and we just got him a new gaming computer.  For some reason, anytime he clicks on "Content", it crashes the game.  We re-installed the game again and it still didn't work.  If it's a firewall issue, does anyone know what I would need to add to the exceptions within the firewall?  (I hope that makes sense...)  Any other ideas what the problem may be?  Any help would be greatly appreciated!
