wow thanks for all the reponse
Ok first of all i have version 1.5 and the version i installed was V3.0_IJN_sub_mod_Jyunseni i must admit i never looked in the U-Boat MOd since i never expected it there
I just made a new reinstall off the game and start all-over
Does it mather in which order i'm gonna install the MODS?? i wanna use the real Fleet MOD and many other ones :p
