Visual editing not working

Visual editing suddenly stopped working.
When I go to edit the draft of a post the visual editing field is just blank. None of the TinyMCE icons are there. If I click on HTML and then go back to “Visual” it now displays the HTML coded text, but still not with any of the tools for visual editing.

As I don’t know that much HTML myself it makes it hard to write my posts.

Any suggestion what I can do?

Thanks!
