If the company founder Jouni Vuorio (the 'jv') is still around, he should be furious at Macecraft for turning the modern jv16 into JUNKware!
I first used jv16 in the 1990s (when it was called RegCleaner). I just bought my 8th renewal license for jv16 (since 2006). BUT THE NEW LICENSE FAILS TO DOWNLOAD & ACTIVATE.
There is a major bug in Macecraft's New & UNimproved Licensing system.
ALSO, unlike PRIOR versions, current jv16 is a DANGEROUS BUG BOMB!
The NEW version is unstable (released May 2018). I am encountering annoying bugs. Uninstalling it...and demanding a REFUND!
NEW BUYERS BEWARE !!! Macecraft is living off its great old reputation...but the modern Macecraft is just a sad ghost of its former self.
