Unexpected error launching game.

Hi. I have a major issue here.
I played game on my desktop PC for a while and everything was ok, but when i installed it on my notebook, the game crashes when i press "Play" button after logging in.
Heres error message.

"An unexpected error has occurred. Exiting FINAL FANTASY XIV: A Realm Reborn. (2)(3e6)"

Any help ?

Bump. Apparently solved by completely redownloading game client rather than copying it from other PC.
