Apologies for not responding for a while, I hit my max daily post limit.

The error my friend is getting is that it's not recognizing her username or password, not sure which or if it's both. Attempting to login to the lodestone didn't work for her either. I've told her it's likely a hiccup on SE's end and to contact support about it, this is making me think that even more. She wanted me to ask anyways though in case we were missing something.
