Unlocking Battleships

I need to unlock the hood from the game but I can't seem to find the right file. I can't beat the LFN mission 7 so I want to take the easy way out

Anyone who knows how please help.

it doesnt matter if you win the sub or surf. campaign.

There is a SavedGame cheat at download.tidesofwar.net

You can also try looking at the forums for help on any partuclar mission and if you dont find any topics regarding the one you have problems with then feel free to start a new one.
