if you recently purchased 5.8.4.1 and immediately upgraded to 5.9.2.1, where the heck would you find a copy of 5.8.4.1???
my guess is on a P2P.
and where did you “purchase” your key?
something seems fishy. the slysoft site does not post previous releases so you had to have obtained your version from somewhere else. if you’re going elsewhere for the program, it wouldn’t surprise me if you’re going elsewhere for your key as well…
