I have recently updated my site to DNN 6.2.3.  I am hosted with Network Solutions who uses IIS 6 and SQL 2005.  I am able to install third party extensions and they correctly display in my modules window.  The problem is whenever I go to add the module I click the button and nothing ever happens.  It seems like there is something preventing me from adding third party modules to any pages.  I have tried several different modules on several different pages.  There is no problem when I try to add a DNN moduel (HTML for example), just when I add my user installed modules.

I don't know if this is related, but even though I am running DNN 6.2.3 it is telling me that there are updates available.  Is my whole install bugged somehow?
