The WOZ tool is distributed as freeware. You have to pay no money for it (if you did, you were fooled). If you like, drop me a mail that you are evaluating or using it, so I can see if it is of any use. The drawback of freeware is that you have no warranty at all. If you run WOZ, do it on your own risk and responsibility. I do not promise any support or help. I do not even guarantee that WOZ doesn't harm your computer or other programs. WOZ is a result of my spare time, so just take it as it is.
