Hep me...

I need some help with a Reba I just got.

A) what year is it? It says Reba race on it, is a 29er fork, and is 9mm axle. Has rebound, compression (gate), air spring, and lockout. I'm guessing 08 or 09, but I'm not sure.

B) The lockout feature does not work. I can turn it, but nothing changes. I cannot turn the "gate" knob in the middle, which I assume adjusts compression. I found a user manual to remove the damper, but what would cause the inner knob to become fixed, and the outer to not do anything? I'm considering sending it to push or something, but I'd rather not, as I'd really like to get a 20mil eventually, so a cheap repair is best.
