Call me kooky

For the sake of poor fools that come looking for a fix to this problem, I’ll post this. DDO uses the .net framework, and the .net framework uses the proxy settings from IE. Yes, this whole issue is due to the proxy. Not sure what exactly the problem is, but if the proxy is enabled in IE you can’t login to the servers (avoid poisoned cache maybe?). The DDO launcher will happily check all the data it needs to launch, and even download/apply updates, but it won’t login and the error it gives really doesn’t help. So there you go, turn off the proxy and you’re good!
