Stuck with the worm in Chemical Storage (German version)

[Mortitia]

Hi there,

I really love this game, but got stuck and am so tired of trying to get out.
After Lake Utuqao I went to the Chemical Storage in the upper left. After going through the door, a worm comes out. So I run through the next door and close it by pushing the button. Then I walk through the acid and the next door and close that one, too.
There are two wooden fences then, each has two "parts". Thats my problem:
Either the worm kills me since it takes too long to break the second fence or i Just broke it and the worm gets me when I'm smashing that wooden column. I just cant make it in time.

Has anyone a good hint for me or can send me a saved game when save?
I'm playing the German version.
