Neat Video & Neat Image community

I just was told that I have to upgrade to pro because I am using HD video. I hit the upgrade button and put in the user id and password that I was given from when I bought the home version and I cannot log in..what am I doing wrong? How do I upgrade to the pro version quickly

To upgrade from Home to Pro please log on to the Home download area and then use the upgrade offer there.
