Unfortunately you are not able to play this A.V.A. Version!
don't be sad, because there is already a Thailand Version
, note that this will provide you a much better connection to the server
so much more experience and fun while playing A.V.A., and gonna make your game run smoothly.
Thailand A.V.A. Version
can be found here.
Make sure you also visit the Thailand A.V.A. Version Forum here.
Hope this info helped!
