Upgraded to Win 7-64 and downloaded the latest (7.1). It doesn't work so well as the previous version did. First off, 2 buttons are greyed out so I can't convert to them. They are greyed out even before a source file is put in there. This did not happen before. I know I can get to the mp4 through the devices but for some reason, mpeg to apple Ipad gives an internal error when I do that.
