I just downloaded the game client and launched it through my desktop.

It says it downloads a file called "1.51.32.RTP" and it's a 430 MB file.

Where can I download a patch and install it on my own?
And if I cant, is there a download which I can start playing right away?

PS - I might have downloaded an older client, here is the one I've downloaded
(It says up on the launcher that my version is 1.51.31(0510).

Help much appreciated.
