When you launch the Pokémon Trading Card Game Online you may experience an immediate crash, resulting in the game unexpectedly closing.
This may be caused by a corrupted or redundant file in the TCGO installation directory.
Typically this is resolved by performing a "full" uninstallation of the game. Alternatively, the "LocalizationDB.db" file can be deleted, which is found in the application/game directory:
C:\Users\YOUR USER NAME\AppData\LocalLow\The Pokemon Company International\Pokemon Trading Card Game Online\
Library\Caches\unity.The Pokémon Company International.Pokemon Trading Card Game Online\
This PC\Device Name\Internal storage\Android\data\com.pokemon.pokemontcg\files\
iOS: (Need "iExplorer" program to browse the files on the device, which can only be performed for apps that were installed from HockeyApp.)
Device Name\Apps\Pokemon app\Documents\
