Admin_message conflicts with TinyMCE

Hi,

Just installed Admin Message module on my live site. Adding a new message works great. But the editing of that message is problematic.

I have TinyMCE module installed. When I go to /node/123456/edit for that message, page freezes as a blank white page with a display of "Disable Rich Text", which is one of the options of TinyMCE.

This error occurs even when I try to edit that node with "Superadmin2 account, which doesn't have access to TinyMCE editor.
