I downloaded the Beta version of DirectRT for Vista and have tried to get it to install on my Vista computer. I've even enlisted the aid of my tech support people at school. I have the problem where everytime I open DirectRT I get a new / different authorization code. I've followed the steps suggested on the forums (in terms of giving read / write permissions etc., trying to download it again, and I am getting nowhere. Suggestions?
