I have installed the Payment Buttons for Paypal into Expression Web 4 and am able to start the add-in but cannot activate it. The serial numbers boxes will not allow me to paste anything into them at all. When I manually type in the digits they enter into the boxes in a reversed order. I have tried to then type them in backwards and still get the activation error. I have uninstalled and reinstalled the addin several times and also DLd a new copy with the same results. I have attempted to install on my laptop and get the same result - won't activate.
I am using Windows 7 running under admin.
