Hello,
I've had the same problem that you guys had re: "String Not Found". Since I was playing the game on my 52" TV, I was in absolutely no position to even try to use the standard game font. Using Xiskio's mod v.8 yielded great results however some elements did show "String Not Found.
After examining the mod and comparing it to the game's default data I came up with two possible solutions:
(a) Either copy the contents from: String/ and Window/ into your mod-v1.19/Xiskio's Font Mod/ (or whichever directory you have the mod installed in), and overwrite the existing contents of these directories.
OR
(
Try erasing String/ and Window/ from the mod directory, this will cause the game to only load the Font/ mod directory and still use the default stuff from the unmodified game.
HTH,
Regards,
