After the Floating lights

Does any one know how to get back to where you need to be after the lights or light bugs..the walkthrough says go down the ladder from the green platform, but for the life of me I can't figure out how...and I thought Azada & 2 were hard....at least there you get hints.....
Would appreciate any help...

Welcome to the pond!
The best answer I can give you is to tell you to go to the walkthrough at gameboomers & look at the diagram of the warehouse. I had to make a copy of it to keep track of where I was & where I wanted to go to keep from wandering in circles.
Hope this helps!
