seems to me they need a few tips on how to make an activation system that works here goes 1/ don't use 0 or O in activation codes no one can tell the difference so they have to try both 2/ ask for the code before the download don't let people download and install then find it doesn't work 3/ If you really have to use this type of system have a work around if you can't fix the problem quickly eg: a button which lets you play for 72 hrs until you can fix the damm problem
