Do you see now BOTH the "Addon Manager" AND the "Couatl powered products" menus ? BOTH are needed to see any scenery.
As explained, too many times already, whenever you see a problem, is NEVER (ever) a problem with the activation or the serial. If you don't have the activation for any reason, the scenery will be all visible, just for 5 minutes at time. If you don't see something, the activation doesn't have anything to do with it, it's just that something in your system is preventing the software to *run*. From your description, it seems that you are repairing your Windows, step by step...
