License Issue is dynamic navison

I am new to dynamic navision.I downloaded Dynamic Navision 2009R2 from msdn and have installed the navision with dummy database available with it. After exploring I tried to create a page but I could not create it as there was certain permission issue .How can I set the a permission to create a custom page.

Hi Welcome to NAV world,

To customize pages you need to have developer licence.

Welcome to DUG!!!

You can not modify the object with default license .,You need to have developer license for the same.

Kindly ask you seniors/partners …
