I previously had the free trial of Sony Vegas Platinum Pro 9.0, but my trial has ended. I bought it in the box at Best Buy, but I can't register it. When I click on it, it only gives me two options- Buy Now or Close. I tried going into the program files and going to application registration, but for some reason it won't open. I tried uninstalling it and re-installing it, but it still opened up as your trial has ended. I dont want to pay $115 bucks for nothing! I dont know my Machine ID or anything because I can't even open it!! Please help!
