I downloaded Sony Vegas 13 the trial version and when i downloaded it the trial was working fine for the 30 days but half of the time I deleted the program to make some space on my computer and when I re-downloaded it it left off at where the trial was at and the next few days later it ended and I was confused because most of the time I never used it and the program was still going and I didn't have it on my computer at the time now I downloaded Sony Vegas 17 and I haven't started the trial at all not even once and soon as I popped up the application it said my trial version was already over and I haven't used it once please help?
