Forum:Depart Rift Station

when i defeated Benezia and took care of the hot labs, i try to use the tram to complete the mission, but when i should arrive at the Normandy,after the loading the screen stays blank. not absolutely, i can see something, but it's very dim, so i'm not sure where i am, i may be on the Normandy's bridge. anyway, i can open the menus and if i try to run, i can hear the footsteps, so the game seems to be running, but i can't continue the game. i tried to use cheats to travel to another location, but from this point everything is dark wherever i go. i tried to use cheats to travel before using the tram too, but this way the mission wasn't completed.
