Mine is version 8.0.138 and is working just fine.
I too, am usually cynical with free programs but not with Grisoft in this case. It has been commercially proven that free basic programs with paid for deluxe options generates a lot more business than deleting a free version and replacing it with a paid for version.
If, for instance, Answerbank would offer a version that bypasses all those advertiser connections that slow the site down to a crawl, quite a few wouldn't mind paying a few quid per month for an ad-free version. But if the whole site would become a paid for only edition, most members would say goodbye.
