It seems to me you are using some DLL and that requires Full Trust.

While your the server where the Application is hosted does not allow full trust. If it is Shared hosting you need to contact the Hosting people and tell them you need Full Trust for your Application

And if it is not a Shared hosting you can edit Web.Config as follows

    <trust level="Full" />
