Form ,Transformation Object Metadata does not exist

Hello developer,

I have a problem doing the form transformation.

I built a simple simple form based on the contact table 5050.

After exporting my new form 50001 as forms.xml and transforming the form
with the transformation tool - importing the pages.xml and compiling it - it is
not possible to start the form in the RTC.
Executing DynamicsNAV:////runpage?Page=50001
The Error message is: Object Metadata does not exist.

My licence has already updatet by Microsoft and uploaded to the database with the classic client.

Thank you for your help
