My Japanese account signs into PSN, but the store isn't working. I am not getting any error number on the screen which makes me think the store is still offline. My Hong Kong account won't sign in at all, still getting the maintenance message.
Only the PAL areas and US stores are going live today
Hong kong and asian areas no word yet. I guess by the end of the week
I download some stuff off my list later , once the store under less traffic
Welcome back pack going to be added in the future i guess next content release.
