Trail Version was activated with license but apps show created by evaluation version

I used the trial version to create an app with atleast 10 forms. Then when the trial expired I used the license I have from scriptcase to activate. But on running an app, it says created with evaluation version.
Another question : how to make back up of the created apps. For example I create an app, then I want to reinstall scriptcase, so how to backup the app which I can develop from where I left off ?

Try to delete your generated code from your system, and regenerate your application. I think that should resolve your issue.
