How to active modules PDF Architect 7 Professional after purchase?

I have just purchase PDF Architect 7, but have no idea how to activate the modules. I cannot find the information regarding the license number anywhere. The Manual does not help here at all. I urgently need access to the modules, but encounter the same problem as with my purchase of PDF Architect 6. Why are the modules not automatically activated if I am purchasing a full license? Don't these extra steps.

Please respond urgently.
