It is a great program. EQ 5 has no limits. EQ 6 had 4 activation's. EQ7 has unlimited loading to computers but only 2 computers can be active at one time and they must connect to the internet 4 times a year to verify the activation.. These are necessary to prevent illegal sharing of the program. I still have my EQ5 classes I wrote. Ask me any questions I will be happy to answer them! Luann
