The Shippack 2 mod works fine for me.
My only problem is how to use the spare slots for ship cloning.

You need to add entries at two places in chief.ini. Lines should be like this;

Ship0 ships.Ship$Ship0 2 icons/shipDestroyer.mat

[ShipPack.Ship0]
com.maddox.il2.objects.ships.Ship$Ship0

You can see where these lines should go in your existing chief.ini.

If this doesn't solve your problem than take a look in your Logfile and see which error is reported than we will see what should we do.
