I received the p2e registration in a zipped attachment folder. When I open the folder and try to extract the file I get the following message. "Windows has blocked this file to help protect your computer" Windows blocks files that are marked as not trusted. I've tried to save it from the zip file to another location and it will not allow me to do that either and I've tried to go under properties of the file to unlock it and since it has not been extracted I can't get to it to save it. Can anyone help with this? Thank you! Trudy
