Changing Name and Number of Sub ?

[kwbgjh2]

I want to change the name and the number of my sub. I have finished 1 patrol and the savegame is IN harbor. The old name of the sub was USS Silversides (SS-236) and the new one should be USS Greenling (SS-213). I found the old name name in the following files of my SH4 folder:

...\data\cfg\playersettings.cfg
...\data\cfg\UPCInitial\ActiveUserPlayerUnits.cfg
...\data\cfg\UPCInitial\CareerTrack.upc

...\data\cfg\SaveGames\00000009\ActiveUserPlayerUn its.cfg
...\data\cfg\SaveGames\00000009\CareerTrack.upc

...\data\cfg\SaveGames\00000009\UPCInitial\ActiveU serPlayerUnits.cfg
...\data\cfg\SaveGames\00000009\UPCInitial\CareerT rack.upc

In all these files i changed the name from "USS Silversides (SS-236)" to "USS Greenling (SS-213)" but always appearing the Silversides.

What must i do to get the sub i want?
