Brightwall Glitch?

[FloFlo]

Hey guys

I can't sprint in Brightwall anymore, neither can I pull out my weapons. I know that I could do this before, but for some reason I can't do it anymore.
Any ideas what caused this and what I can do about it?

Thanks a lot, help is really appreciated.

Wow. I fixed this glitch by winning a chicken race. What the ****.
