This just in! even version 3.1 telling me the same thing. It wants to re-format my Hd-5. I have no idea what version I had before I just know I downloaded in 2011 and I don't know what version was out at that time. wait a minute. I just installed 3.1 on a different pc with windows xp and its giving me no problems except for the usual authentication required prompt, but since the sony connect store is down I cant authenticate that pc, meaning that's useless.
