not too long ago. However, the transition hasn't been as smooth as many hoped. There are sporadic reports of system hangs during the initialization screen, post 1.3 update. While EndSights says "many systems" are affected, it seems likely the problem is isolated to a minority of PlayStation Home users.
According to Home Manager Locust_Star, a few items in the virtual world may be causing the hiccups. Items like the Namco Bandai Love Seat, Fat Princess Throne and Ghostbusters Bagel are amongst the few suspected to be causing crashes. Until a proper patch is implemented, the PlayStation team recommends deleting and reinstalling PlayStation Home. Erasing Home data from the Save Data Utility may also help PlayStation gamers that are desperate to log into the virtual world.
Let us know if you've been affected by the latest Home update, and if these workarounds, um, work.
