Typekit

How do I disable typekit. It's interfering with all my desktop files and I don't want that. I'm having to assign type everytime I open a file. That's never happened to me before this Typekit and IU'm also getting this error. Please see attached image. I asked this question a couple days ago and someone responded saying it wasn't a Typekit issue but something else and I beg to differ.
Please just tell me how to get rid of Typekit and I'll be happy.
Thank you
