I was having that problem, too. Uninstalled station launcher, tried following our PS installation guide '11, but it would never get done patching the launcher. Finally went to
http://www.soe.com/getthegame/?locale=en_US and aaall the way at the bottom, next to PlanetSide, there is a small link that says "Returning user? Reinstall", clicked on that and it gets to the point where it wants my subscription info, which I expect should go away once the 30 days thing finishes rolling out a cross all accounts by midnight tomorrow.
