Unfortunately the lyrics server api has been disabled for the moment, Im not sure if it will become available or not so for the time being you should not run the Correct Lyrics task or it will put
<a href=http://lyricsfly.com>Find lyrics on LyricsFly.com</a>
into your lyrics field.
Correct Lyrics is also a default task in the Autocorrecter so you should remove it using Preferences:Manipulators:Autocorrecter
Sorry for the inconvenience.
