Doesn’t seem related to this plugin. Once deactivated, TinyMCE Advanced cannot affect the editor (or anything else) on your site.
Make sure you delete the browser cache and try again. If it still doesn’t work, check for JS errors in the browser console: http://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors.
Hello, I am also having the same problem.
See the error that the browser console reported:
Consider using 'dppx' units, as in CSS 'dpi' means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual 'dpi' of a screen. In media query expression: print, not all, (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)
