I tried the trial version of 4.1 edited a couple of videos of my son playing football. Worked fine then purchased the 1yr subcription, but now I can't remove the watermark, nor is it allowing me to burn a dvd. This worked before and I got the watermark, which was ok, but now that I've purchased it I would like to remove it and be able to burn dvd's. It goes through the burn process, says complete, but the dvd is blank
