If the game fails to launch after the update, ensure you copied the contents of the TENOKE folder into the main directory, not just the folder itself. To give you more specific advice, could you tell me: What is the name of the game you are trying to update? Are you on Windows or using a Steam Deck/Linux ?
: Crucially, check the box that says "Copy contents of crack directory to installdir" (or similar wording) to ensure the updated game remains cracked.
