I have not downloaded this software, but it looks suspicious. The file size is 13k, which is very tiny and it doesn't seem likely that it would be able to do what it claims in that small a file. Also, the developer's site doesn't work and there is no developer information. And version 4.0 is the first version.

If the developer reads this, you might want to update your information and check that the file is correct. I would caution anyone else from trying this program until more information is available.
