It sounds like the install didn't finish properly. I can set up another screen sharing session to help you get it installed. Just post your US phone number or Skype contact information and I'll contact you directly.
I'm not sure if you are serious about webassist is being real. There are tens of thousands of forum posts with us working with customers directly and them being successful on our forums... surely you don't think they are all fake? We don't delete any posts, positive or negative (other than spam), so you can literally see every issue we have had for the past 10 years.
I'm honestly not sure why it isn't working on your particular machines. I'll work with you to try to get it installed properly when you post back.
