I get the following error when trying to load the file Manager for the Site, either by clicking file manager from the iconbar or selecting file Manager from Admin menu.  I am able to open the file manager from the Host menu.

Below is the error from the log viewer.  first the Module Load Exception and then the Page Load Exception.  I am not sure what has changed since this was working yesterday and I made no changes to the site.

Module Load Exception.

Can anyone help me with this?

It was working previously and I have other websites with . in the name.  I have a replica of this exact website on my development server and am not having this issue.

The webserver is W2003 so the the Network Services account has RW privileges to the root folder and all child folders.

I don't think it's a permission thing. 

Is it possible that the File system and database got out of synch somehow and that is what is causing the problem.  If I change the name of my web folder to remove the ., how will this affect the file/database relationship?
