This is the error that shows when entering the form where the geographic coordinates field exists.

It will be hard for anyone to give you a solution without knowing what the problem is. Inside your GenioMVC folder there's a file named "Web.config", in that file you should have some lines of code like the ones below:

<customErrors mode="On" defaultRedirect="~/ServerError">
    <error statusCode="404" redirect="~/NotFound" />
</customErrors>

Change the mode from "On" to "Off" and publish the solution again, this will give you a more detailed error message and, hopefully, a better idea of what the problem is.
