Cufon Plugin Disappeared

Hi,

I’m just getting started with WordPress and I’ve run into a problem that has me mystified. I activated a font-replacement plugin Cufon that worked perfectly. Then I activated a visual editor called TinyMCE Advanced, which also worked perfectly. Both were working perfectly fine together and I decided to change the js font file I wanted to replace it with. However, now the settings page for the Cufon plugin has just disappeared. It still is recognized and I’ve tried de- and re-activating it. Deleting it and re-uploading it and for some reason it won’t appear in the Settings list. Does anyone know what could be causing this? Thanks so much.
