As I am not accountable, ordering programs and training materials on the site and downloadable cannot be considered a commercial contract. Take it as sums given to donate my work and expenses.
The databases listed below are all fully functional. You will receive the download link when ordering. Once you have downloaded the stored, compressed information (except for versions sent on a flash drive) and paid the support amount, I will send you the password needed to extract the file.
You can order my training materials by clicking on each training at the company that appears there.
