Playing other versions

im trying to get onto the PH version. anyone have any suggestions?
i tried the guide for EU/NA seeing as they both say same thing, i figured it might be the same for PH, but isnt working for me.

ive managed to get in using the same method for EU/NA, but it is horribly laggy. any suggestions?

I tried using both versions and they tell me that i have to reinstall the game.
