Thanks gazz for your answers.
I'm going to try to reinstall the mod, and we'll see what happens.
and congratulations for this great mod

(and for the others too !)
edit : I tried to reinstall complex cleaner manually and as soon as the message about the aldrin stuff appears ("Fixing the aldrin mess"), all the complexes were dismantled. I guess I'm going to reconnect them manually.
news from the front :
it's awful. My complexes are created right in the middle of the sector as I explained yesterday.
For one of them, it's even built ON the plutarch HQ (I let you guess the mess this can trigger). I don't manage to move it to a safer position.
When you use the "relocate" function, the map of the universe appears, then you choose the sector and finally the position you want (Am I wrong ?).
But when I choose the position, nothing happens (should an icon appear on the map where I clicked ?) although I get the vocal message saying that the complex has been relocated.
Has the "relocate" function been translated into french as the others were ? (doesn't seems to on the french thread)
If nobody has an answer, I guess I'm going to wait for 2.0 upgrade from steam (next year maybe) before playing this savegame again, cause every factory explodes, one by one
