Ah-ha!!! The U-Boat Missions Add-On... There is your trouble. btw - you shouldn't need to do the v1.4 update before the v1.5 Add-On, ~BUT~... you will have to contact Ubisoft Support and request them to re-set your license. The last time I re-set mine, it took them like 7 or 8 days to respond. The last time I remember someone else doing it on SubSim here, it took them like 10 or 14 days for them to respond. Who knows how long it will take them this time... They will most likely suggest you purchase the full SH4 Gold Edition, which is easier to deal with... it usually runs about $10US, sometimes on special for $3US.
