Never heard of Ladyhawke before today (the movie is another story. I saw that in the theater!) and loved her music. It was a welcome change to have some new stuff to listen to today. I may steal a banner and add it to a site or two I have. :)
Wordfence will still alert you that it needs an update, it just wont happen behind the scenes automatically. And. yes, you should be able to update it like you would any other plugin.
Oh, and I was asking that in case you had to ssh or ftp to the server and replace the plugin. You can probably do it through the update interface just fine.
