Hi. Downlowded new X15 and installed it. Used it 3 or 4 times. Next day the intro picture "Magix X15 ...." came as usual, but froze. Restarted, and it still froze - every tine. Reinstalled the program, and the same happened again and again. A box appered saying - A SERIOUS PROGRAM ERROR OCCURRED -error in module "video_pro_x_exe" Any HELP????
