If I save the date or any other parameter in a sav file this could be
cracked.
Using a large amount of random numbers and a few numbers at known
position that hold the starting date of the
license is a good idea. I think I'll use that !
Similarly I can store the date of the last time the software was used.
Also I could use another kind of "cryptgraphy" but I think this is
more dificult.
Thanks
