I cannot figure out why I am receiving this error.

I recently upgraded to IIS 7 and SQL database via my Godaddy shared hosting account. I was informed after the upgrade I would need to update my connection string in the web.config file. After the server was setup and ready, I changed the connection string and the site launched just fine. This all happened about a 2 weeks ago.

DNN Version: 4.05.01
IIS 7.0
ASP.Net Runtime Version: 2.0/3.0/3.5

When I login as host and try access the Admin Site Settings I receive an error:


Here is the error code (in bold):

Any help is greatly appreciated!

The host settings tab gives me the same error. I did try to clear he cache with no success. I noticed some large database tables, so I truncated them. It could be the DNN store module tables, they are quite large and I don't know how to shrink or truncate them.
