CLM 10 : Cannot create Contract Document template

Hi Gurus

We are implementing CLM 10 SP03

I created docx clauses and sections, I have full authorizations but when I click on "new" under CD Template list query the system displays the workbench instead of the Template creation screen.

What can be wrong? No error message appears.

And how can I check the DOCX generation service is running properly?

Thanks in advance
