So I removed the caps, compressed the fork, inserted hexagon rod to adjust rebound, and it won't turn either way. I know you have to wiggle the hex around a bit to make sure it gets in there...

I had it set at slowest setting for urban riding, now I want the rebound to be faster (counter-clockwise, according to manual) but it won't budge.

Anyone else have this problem?
Tips, comments or suggestions?
