Content Editor not rendering for new Content Type

I am a new user to Percussion CM Server. I have just created a new content type and associate templates and made the templates visible the content type, the communities, etc. When I go create a new content item of the that type, in the browser I get the error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

The top of the stack trace I get from the JBoss server looks like this:

17:06:04,317 INFO [PSServerLogHandler] appid: 0 type: 1 time: Thu Jun 24 17:06:
