It doesn't work. I tried that too but it just updates the launcher to the 08/04/14 version, which I think is the second beta launcher. Its showing up in the store front now rather than just searching for it so it should definitely be live. Some PS3 users had these issues for a while, I still haven't found anyone stating a solution so I guess its just a case of waiting for them to fix it, which I hope they do soon as two botched launches for the same game isn't doing anything to boost confidence

Edit: And now the download is taking a lot longer, was 20mins to half hour last night, now showing over an hour
