I got up to the partt right after finding the crowbar in the alleyway full of zombies. I used the crowbar on the door and went to the second floor, looted the flash light and batteries and vodka, then left and went to turn on the radio then out of no where a random fast as hell zombie appears and kills me pretty damn fast. Then it gets stuck on the "MM" loading screen and doesn't "continue", just gets loading until I manually have to close it with task manager. Anyone know what to do?
