I'm having this problem as well. PS3 version.

Since the update, I haven't been able to get into the game on PS3. Sometimes it will let me log in and get as far as the main menu before it tells me the server's not responding and kick me back to the launcher, which will load the frames, but not the login boxes or news/topic highlights.

Sometimes it will tell me to register the code that came with the box (already done a month ago) and then bring up the following message:

A system error has occurred: -2147309046.

Or sometimes I'll get this:

Unable to complete version check.
[20447][20448][10009][10019]

Or this:

The server is not responding.

Yes, I know there's a link right there for their customer support. I already tried it, it's utterly useless. I try searching for the error codes it gave me and it says they don't exist.

If I continue pressing X to try and get in, it just keeps feeding me error message after error message. I was able to sign in every day with no problems before the update, but after downloading and installing it, my game is pretty much dead.

I even tried deleting the game and reinstalling it, but that didn't fix it at all.

Is there any way to fix this? I just finished my free month and paid for a subscription, so now my money is literally being wasted on a game I can no longer play.
