If you build your own version of the game you may find a problem with a subscript out of bounds, if this is the case look in the languagebank\english\textfiles folder and modify fpsc-050.ini so that the number is 629 instead of 625, now open fpsc-050.txt and add lines to the end of the file like this -
626=A
627=A
628=A
629=A
This will stop the error message from displaying
In order to fix the Multi-Player
Expanded fpsc-050.txt by adding more entries (630-644) and changed fpsc-050.ini to 644.
Thanks Goes to Scottie for this fix
