I am also have this problem, interesting thing is I have 2 accounts, one works fine and the other does not work??
Ringing SCEE help line now!!
I only found this issue yesterday tried to buy and download a game for my psp only diffrence is each time i click download after i bought it it just says "Thank you for your purchase" same exact issue with the download list thoe i get a nice error code, what i looked up wich is for when it cant connect to the network.
Hey everyone, I don't know if it's just me but it's back up and running now for me. You guys should check yours out too
sweet ill go check mine now let u know how it works out, hope it works really want my game i paid for.
EDIT: Yep mines working im gonna make the assumption now since we can confirm 2 ppl atleast are able to acess there downloads list that they have fixed it.
