Can you connect to this site at all...
http://forums.station.sony.com/station/forums/show.m?forum_id=200 The Station Launcher guys are pretty good at trying to get issues sorted.
My personal suggestion would be to remove SWG and the Station Launcher and reinstall SWG because it sounds a lot like a conflict between the two somewhere.
Outside that I am assuming you have no internet issues or problems with other games?
Oh and what operating system are you using?
