Does PDF Architect need a special activation code?

I installed and re-installed PDF Architect, along with PDF Creator.  When I attempt to open PDF Architect, the logo flashes briefly, then disappears.  The program will not open.

Am I missing something?


we havn´t heared about this so far, please try to uninstall the PDF Architect, do a reboot and install the latest version afterwards. An activation will still be neccessary afterwards (activation of the create module is free).
