Gotta Brain cramp/stuck

[logbo]

I'm stuck after the room in the KANAL where you turn the red valve to fill it up with water. Then crawl through the pipe, break the boards at the bottom of the pool. Jump across the pool and out. The game auto saves here.
Next area I can't find a way out. Long narrow canal, get a couple of guys coming down a rope, then a round room, up a ladder, cross boards ect. and dead end. Ran allover the place but no out. :sniper:

Ok... so you climb up the ladder in the round room and go accross the planks... keep looking down because there is a wall separarting the original side where you climbed the ladder and another side that leads out... jump down after going accross teh planks... !
