I’m always leery of those. They sel. Them on Amazon too, but reviews are really mixed on them with folks saying they got ripped off, while other s say it’s legit. Like on eBay, I note they range in price fro around d $29-99, which ones are legit? Hard to tell, so e folks say that the product key needed to register them don’t work. It’s a gamble I think. But worse comes to worse, I’ll give it a go, thanks for the link
