I've been running an up-to-date version of ZoneAlarm Pro, but allowed the licence to expire before renewing. I paid online for a new licence, but in the meantime I had a disk crash as a result of which I lost my ZoneAlarm program files. So I've re-installed an earlier version (6.5). The intent was to introduce the new licence, then upgrade back to the latest software and def files. The software takes my licence key and tells me it's valid, but as soon as I clock on OK it displays the previous licence key and tells me I'm out of date. Can someone help, please, as I seem to be stuck in a Catch-22 situation where I can't update without the licence, but can't licence because I'm out of date. To make things worse, downloading from scratch from ZoneAlarm doesn't work because newly downloaded versions crash my PC. I suspect this is because my old machine is still at XP Service Pack 2 (it's too old and creaky to upgrade to SP3). Can someone help please?
