Basically I want my all the users to activate (online or offline) every 60 days. Please help.
Well, in that case use IsGenuine(60,14,false,false);
If "skipOffline" is true then TurboActivate will never verify with the activation servers if the initial activation was done offline. If "offlineShowInetErr" is true and if "skipOffline" is also true, then if IsGenuine(x,x,true,true) fails to connect to the activation servers it will return an "internet error" rather than a success (which would happen if "offlineShowInetErr" was set to false).
Does that make sense?
