PLEASE HELP (dwarves and Doguns part 1)

Hi, im at the part of the quest where I have to go through the east part of the base and get a repair kit, I accidentally went through the exit. And now when I tried to get back into the coalition base, the4 whole dialogue plays and the guy says I can come in, but it never lets me through the tunnel. Ive tried reloading, /kill, /class. Please help.
