OK,
I found the cause of the CTD.
...\SilentHunter3\Data\Submarine\NSS_Uboat2B.
So, the only thing, for the while, (because it only resolves the problem halfway) to make the v7 to work correctly is to remove the directory "NSS_Uboat2B". I'll investigate more deeply later what file cause the trouble.
Let's go to reactivate all the gas machine...
