Hi Chris & Flyer13 - no it's a full version. I've had it now for a few months actually. The zip opener worked just fine until about 2 weeks ago. I went to the Microsoft help site & posted the same query. They came back with a lot of instructions I didn't really understand, but I had the impression it would be quite easy to re-activate the zip opener if only I just knew how to follow their instructions!!!!
Maybe it would be just as effective (& easier?) to download a freebie zip opener as you suggest?
thanks anyway,
david
