Followed the directions, and does not seem to be working. The Additional Descriptions box in the Product page of WPeC is still just a normal text box with no added features. In the normal editor (with the VISUAL / HTML views), nothing shows up in the VISUAL tab, while HTML tab displays correctly.
I have read that it could be a plugin conflict, so I've deactivated all plugins except TinyMCE for WPeC and the main WPeC plugin. The issue still exists. Anyone else have any ideas or are experiencing a similar issue?
