Following the tutorial, I copied in all the appropriate files to my web root.  Using the default /cs sample, I get the following. Any idea what's wrong?

asp.net Chat http://cutesoft.net/ASP.NET+Chat/default.aspx
Web Messenger: http://cutesoft.net/Web-Messenger/default.aspx
asp.net wysiwyg editor: http://cutesoft.net/ASP.NET+WYSIWYG+Editor/default.aspx
asp wysiwyg html editor: http://cutesoft.net/ASP
asp.net Image Gallery: http://cutesoft.net/ASP.NET+Image+Gallery/default.aspx
Live Support: http://cutesoft.net/live-support/default.aspx

Unfortunately that solution didn't work.  I created a new virtual directory and copied /bin, /cs, /cutesoft_client in and it worked fine, so it would appear that it is something in the configuration of my existing site.  I'll continue to investigate and post any findings.

Figured this one out.  Long story short, we had an httpmodule that was blocking some of the requests cuteeditor was making (and it makes a bunch!).  Once we told the httpmodule to ignore all requests going to the cuteeditor folder, it worked fine.  Thanks - your post gave me the spark I needed to find this problem.
