The reason for your difficulty is based on 2 separate set-ups.
Either you download the Thai version via their own download which can take a while or you download manually the files bit by bit.
Many people have the same issues your having due to cross file formats. some downloaded through Thai's server and other files through another fire sharing site causing the game to not load.
My advice is to download the game through the Thai server. Once complete restart PC. when you load up good games launcher do it through the actual launcher in the folder for the one time set-up. It should load now and show your game now in its game options.
Again you will need time to download necessary updates of the game but these will be automaticly done for you like you did to start of with.
Load the game enjoy
anyone got any fixes for the thai versions? currently downloaded the game and GoodGames however the play button when clicked does nothing apart from bottom right saying: program is running, double click icon to open, for GoodGames. I've tried opening using admin but that does the same and via the launcher itself but that does nothing
