For a cracked game, the language settings are usually changed within a text file. Not all cracked games have their language settings in the same, exact named file, folder or subfolder. You would need to go to the installed game's folder and try to find a text file that is called either "steam_api.ini", "steam_emu.ini", "settings.txt", "settings.ini", "language.txt", "force_language.txt" or any file with a file extension of ".ini" or "txt". Sometimes, the name of the Scene or P2P group that cracked the game is used to prefix the name of the text file that has the language settings like "RUNE.txt", "TENOKE.txt", "FLT.txt", "RUNE.ini", "TENOKE.ini", "FLT.ini" ... etc.

Search in any subfolders, if necessary (The text file might not be in the installed folder's root directory) and then open it with Notepad. In the text file, do a search for the key "language". If it is found, set the key's value to a language that is supported by the game (eg. - language = english, language = tchinese, language = japanese, ... etc. Check the game's retail page for supported languages to make sure that the language that you set is actually supported by the game), save the change and then try running the game again.
