I have the FREE version of ZA, but I keep getting a pop-up at start-up telling me my registration has expired. Does anyone know how to get rid of this nagware? I've been using the free version for years, and this just started 2 days ago... I do not want/need the PRO version, as I am quite happy with the FREE. Thanks for any info.

Operating System:Windows XP Home Edition
