So, I started getting this error about two days ago from the today, the 13th. From what I have seen myself, and heard from other players, is that this error prevents you form editing your heroes and also form activating new heroes. The error is not just me, but everyone on the servers, also it affects Steam and Origin users alike. Any ideas would be really appreciated, as this error basically prevents you from advancing without being in a party with high level players. I don't know when the earliest report of this error was, but it hasn't stopped once since I first got it. I saw a player who just bought the game, but couldn't activate their third hero because of error code 3, and so he couldn't play at all.
Sort of unrelated, but I've been playing with someone on threat level 2-1 (I'm on 11-1), i got him up to 7-1 over the time the error has been up. The problem is that his heroes are still level 10 to 15. He stands no chance against the threat he's on now, and can't customize because of the error.
Once again, any help will be appreciated by all current players, I consider this error to render the game useless, until it's fixed/goes away, Darkspore will have lost much of it's playability.
