You should be able to change it through your preferences. Click on the Editing tab and make sure the "Preferred editor" menu says "Classic rich-text editor (where available). If that doesn't work, you may have to use the "VisualEditor". I've got mine set to "Source editor" because I'm used to going in and cleaning up code that the other two editors seem to leave behind.
