I am having a problem with installing DNN on my customers site.  I've done this many, many times before and this is the first time I've ever seen this.  The install goes just fine, but when I login and go to either the setting on the admin or host menu, I get the following error. I've reinstalled both the files, and database, and reset the permission about 5 times already.  Like I said, this error only happens on the two settings pages.  The rest of the site works just fine.  I can get into modules, install modules, get to skins, install skins, set skins, use all the modules, etc, just not those two pages.  Anyone know what I'm missing?

In addition to this, since I can see "System.Security.CodeAccessPermission", I believe this has to do something with the asp.net trust level as well. Can you confirm the trust level that your website is running in?

The site is running in Medium Trust.  Godaddy doens't let you change this.  I run many other sites under this same trust. =)
