Lotto Sorcerer is released as "shareware", which basically means that you get to try out the software before purchasing. That way, there is no disappointments.
Lotto Sorcerer, like most shareware, limits the evaluation version in one or more ways. Lotto Sorcerer is limited to 12 uses, which should be ample time for you to evaluate whether you want to continue using it.
If you wish to continue using it, you need to register the program by purchasing a license. When you purchase a license, we will send you a serial number and registration code. When you enter these, along with your name, in the Registration Window, the shareware evaluation version is immediately transformed into the full, registered version. Note that no software is sent, only the serial number and registration codes.
