I installed the November issue's version of PC Tools Int. Sec. 2009 on to my laptop when it came out, registered it with the promo code from that mag and all was fine. I have now installed this issue's version on to my desktop PC and again all was fine, registering was simple. However, I had to re-install XP on my laptop and wanted to keep the November version on it, but I cannot register it, as I no longer have the mag or disc. I tried using this issue's promo code, to no avail. Can anyone help?
