Thank you Nanaky, This worked for me. I had tried uninstalling and re downloading the latest version of ADE 4.5.1 to no avail. I followed your instructions and it worked! Hallelujah! It destroys the pleasure of reading if you have to spend hours trying to get your software to work. Kind regards, Marion
