I just got my new laptop which has XP SP2 and a SATA harddrive. When I attempt to install ZA free (version 4.5.594) the computer crashes. I assume that the old version of ZA isn't compatible with SATA since it works on my desktop which has XP SP2 but not a SATA drive. Anyone know if SATA is definitely the problem and if so what is the best version of ZA that would be compatible with it? Also, would Sygate 5.5.2710 work with it? I am trying to avoid going to the latest ZA version due to a lot of problems I have read about. I have tried Comodo before but didn't like it at all.
