is so, that the names for static have changed, as stated above, you will have to look them up in the inis, for the moving ones it is so, that shippack2 get is's own class, the ships are not found under ships but under shippack in FMB. so the entry must be changed:

for ship pack1
[Chiefs]
0_Chief Ship.Carrier0 2 0 2 1.0
1_Chief Ship.DestroyerKM 2 0 2 1.0

for ship pack2
[Chiefs]
0_Chief ShipPack.Carrier0 2 0 2 1.0
1_Chief ShipPack.DestroyerKM 2 0 2 1.0

another possibilty is always, install pack2, go to FMB an reposition the new ship... pretty straightforward work.
