Good day, I have a 6 Core AMD computer with 16gig ram and a GTX 560ti Asus card running Windows 7 Home Pre. When editing HD my programe gets very unstable and then I cant edited anymore. I then have to reload MX Plus and then it works ok for a few minites and then starts stuttering again and then it gets so bad that I have to reload MX again to go on. Please can someone advice on what is wrong. Many Thanks Wayne...
