i know that , i use macchanger to change the macc address and get unlimited free trials. this has worked for quite a long time , normally if i open it up with the actual mac address and request a trial it tells me my time has expired. now i get the check time settings error message weather ive changed tha mac or not and ive tried on two versions of the software...the macchange hack doesnt work on the newest version , it works with the . 377 version but i had no issues until i reflashed today.
