Insert Module Not Installed or Downloaded in Pro Version

I have purchased the Pro version of PDF Architect and I can not insert pages in to new or existing documents. I get the prompt to download the insert module but, when I click on the Yes button to download and install the module, nothing happens. Please help.

I wonder how many other modules are not installed. There used to be a Modules menu option where one could view the modules and their status.

Please try restarting the setup from the control panel or use our all-in-on installer to fix the issue:

That seems to have solved the problem thanks, Florian. The first reinstall didn't work. I had to reboot and reinstall a couple of times before I got the satisfaction.
