Thank you. No this is not the normal problem where I wait five minutes. The avatar is 100% still logged in to SL, my friend and my alt both see her floating there.
When I attempt to log in the secondlife.com website I get this: "We're sorry. It looks like the username or password that you entered were incorrect. Check that your caps lock key is not enabled. If you continue to have trouble, then please contact Second Life Support and we'll be glad to help you."
My other two alt accounts work fine. Fantesia Freiman is stuck in-world with a suddenly defunct password, and no one is in control of the avatar. I need some kind of serious Linden help here.
