I want to update my Gemini from 5.1.2.3579 to 5.1.3. I downloaded the countersoftgeminiv513.zip and extracted it. I made a copy of the Gemini Web Application on my server that is the 5.1.2.3579 version. I copied the Gemini Web App folder from 5.1.3 over the Gemini Web Application folder for 5.1.2. This is the same process I used to upgrade from 5.1.1 to 5.1.2.

When I opened the web site I got an error. This is from the system log file:

Unhandled exception: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.. Stack trace: at System.Reflection.RuntimeModule.GetTypes(RuntimeModule module) at System.Reflection.Assembly.GetTypes() at Countersoft.Gemini.Infrastructure.Apps.AppManager.LoadApp(String fileName) at Countersoft.Gemini.Infrastructure.Apps.AppManager.LoadApps()

What steps should I have taken to upgrade from 5.1.2 to 5.1.3?
