If your Creator's Room button does not show up, or it shows "Not me!" for your own Creator's Room, do the following:
1.Disconnect from Sudomemo.
If this doesn't work, close Flipnote completely and reopen that.
If it still doesn't work, be patient, and wait for a while.
If it still doesn't work, well, go sit by a lake or something. "Logging you in" is dependent on what's left of the real Flipnote Hatena servers.
