I just downloaded the demo version. If it works, I will definitely buy it; but so far it doesn't work. I tried to add a partition, but I got stalled when I tried to free up some space. I got to the "Increase Free Space" wizard, but when I got to the "select partition" section my partition selection was greyed out so I couldn't select it. Is this because it doesn't work on my computer, or is it because that feature is disabled in the demo version? I couldn't find anything in either the help file or the readme file that explains what is disabled in the demo version. If it's disabled, how can I prove that it works before I buy it? I am using a Compaq Presarion 2210 running Win XP SP2. I have 512 Mb memory and a 40 Gb drive.
