Why was my post removed???

I really don't understand why it's now called "ZA Extreme security" when it was "ZA Pro" before. The "release history" shows this:


Can i install it or not? I have win xp, and not windows 7. Licence is not for "ZA Extreme security", it's for "ZA Pro".

And somebody removed my post here. Can you atleast send me a private message explaining why.
