Followed what it told me to do and stil nothing. Can't login to the store or network, yet others can. I went to the browser on my PS3 and works fine...
edit: , so I just signed into my other accounts and I can get on. I tried my main account and nothing. I don't cheat, swear, exploit or anything like that so did I get banned or something?
I had the same problem early this morning about 2-3am. Tried login in but couldn't, so changed password and it worked. About an hour or so ago I got an email from Sony that said something about suspisous activity so they wanted to me to change my password and so I did. Now I'm getting the same error code you have but at the same time I can login to my account on the SEN website. Just finished talking to customer support and they said that it could be maintenance.
