however the limit of the 7-day test should be on the machine, not on IP of the wifi network. if there are 3 of us in the house, my brother and sister, and if one of us tries the program, the others can not try it... does that sound right to you? or just as in my case, tried on old pc (1 day) now with new pc i can not do other tests if not entering the data of a card there credit ... in my opinion the 7-day limit should be applied to the individual PC in use.
