Right, so the problem is that once I had idled out and tried to come back. I couldn't. It said my password was incorrect, despite I quite well knew it wasn't. Despite that I even tried recovering my password and changing it - with no success. It still keeps claiming my password is wrong. Yet it accepts it when I logged into the forums.
Oh, and I'm trying to connect via browser, in case that's relevant.
Any idea what might be the matter here, all of sudden?
