Yes...the stupid Terminator Salvation elevator glitch...help?

I finally decided to have a go at this game, and read about the elevator glitch before I bought....just didn't think it would happen to me, since it seems to be random.

But anyway...there is a part in the last level (skynet) where you take an elevator down to a different floor. The door opens, but won't let you walk through. Anyone ever find a way around this?

Thanks!

 

I tried that when it first happened, also tried starting over the level...

But thanks for the input.
