Ran this program on my 2 Puters. Windows XP Pro and Vista Business. IMHO this program is nothing but trouble. It is now OFF my Puters. I had to Restore both Puters with Acronis TI to get them to funtion again. Not all is lost, as I now know that Acronis TI restores from an external drive very well, in fact less than 15 minutes. Thank God I had a backup...... Hope this msg is in the correct forum.
