I am not so sure if this is the issue, but you don't happen to have the beta phase 3 launcher on your PS3, do you? Cuz, if you do have I would recommend you to uninstall it before installing the game's client, some of my friends got problems to install the client during beta 4 because of that and, once they uninstalled the beta 3 launcher the actual game's launcher worked just fine.

I got one install error for the newest patch only, but it installed after I re-started my router and client.
