After moving Swift Books from Plzhosts to Total Choice Hosting I noticed the HTLMArea was not working.

Knowing that HTMLArea is apparently defunct I decided to install FCKEditor.

Despite having FCKEditor selected in Configuration \ My Store I get just the raw text editor in the product pages, but in the Define Pages I get

The requested URL /editors/fckeditor/editor/fckeditor.html was not found on this server.
The file definitely exists in /home/MY_USER/public_html/editors/fckeditor/editor/fckeditor.html with permission 644

It looks as though it's a setup problem (permissions or a missing file). Any suggestions?
