I finally got my reply from lucasarts and their reply was to patch the game to version 1.2 (the game is already patched!!!)and they sent me a savegame file o.k.
not so o.k. now I get stuck at the rotating gears no automatic opening door so i`m going to send them another e-mail explaining this problem(they`ll get sick of me soon) i just hope they come up with a solution
that`s all for now
