What am I doing wrong?

So I download the latest dmg from the website.
I double-click the dmg
It mounts PS_install
I copy the folder too applications.
If I try to run either psclient or updater, it opens then closes, saying a bug has occured.
So I try opening the updater in my terminal, and it says:

WARNING: could not load plugin \'crystalspace.documentsystem.tinyxml\'
WARNING: could not load plugin \'crystalspace.renderloop.step.generic.type\'
Failed to load plugin crystalspace.renderloop.step.generic.type; pandemonium will ensue.

Huh?

gne? we have an incorrect version of planeshift so we have to wait a bit for a new client version or for a new working updater ,now it would be cool that you read a bit around in other posts coz it is boring to type the same thing again and again ,thank you

Yes, the latest .dmg on the website is very, very old and buggy.
