I've had to make a new account to post this. My actual account is Eveolene, but I can't log in.
If I try to log in via Facebook, which is what I always used to do, I get this message (can't seem to post an image but screeny here).
If I try to log in using my username and all the most likely passwords, it says they're incorrect.
If I try to reset my password with either my email address or username, it says no account exists with that username/email address.
My account clearly still exists, here!
So, erm, yes, no idea what else to try.
