Gallery Export.iPhoto Exporter locks export on iphoto plugin locks out export in iphoto 9.43

i cannot export on iphoto, everytime i do, a plugin called Gallery Export.iPhoto Exporter locks it. It presents a register splash screen that only offers a register option. if i cancel it cancals all export options - if i register it says i have no internet! Im totally baffled! It never allows we to choose any other export options. When I looked for the programme on my mac i could find no sign of it anywhere. I looked in the plugins folder for iphoto and no sign. I tried copying a version from my other mac into the said folder but no change. Can anyone help? I have never used this plugin and only want to get back file export!
