Hi UscTrojan,

You are getting a BadImageFormatException, which is telling you that one of the assemblies in your bin directory is bad.  The exception indicates that DotNetNuke.dll could be the culprit, or one of its dependencies. 

Check for files in your bin directory with zero-size (or maybe 1-byte or some other wierd size), and also take a look at your DotNetNuke.dll.  If none of these are the problem, you'll have to start looking at DNN's dependencies, one-by-one. 

You might also consider downloading a 4.6.2 package and just copying the assemblies into your directory.  If you do this, however, make sure to back up what you currently have so that you don't create even more problems than you currently have!  I would not recommend downloading a later version than what you are running, except as a last resort.
