Overwritten data... how to fix?

[Generalee]

Hello, I currently have a question and an issue, I will start by explaining the situation.

Yesterday, I have downloaded a whole bunch of surface vessels and it took me a long time to download them all and a long time to scan them for viruses. As I was installing, It showed me the following: "Readme.cfg" has already been altered by the "Playable King George V Battleship V0.2" mod.
"CareerStart.upc" has already been altered by the "Playable King George V Battleship V0.2" mod.
"Flotillas.upc" has already been altered by the "Playable King George V Battleship V0.2" mod.
"UpgradePacks.upc" has already been altered by the "Playable King George V Battleship V0.2" mod.
"Weapons.upc" has already been altered by the "Playable King George V Battleship V0.2" mod.

Along with this:''Enabling this mod *may* have adverse effects on your game. Are you sure you want to enable this mod?

You dont need to tell me that the ships files are modifying the same object, because I already know that, what I want to know is if there is a way to fix that problem (if it would help to add a line, change the script, create a file for each ship ect,ect.) and if so, could someone be kind enough to tell me how to do it.

Thanks
