Users are reporting activation issues. Its not getting activated for many and showing FREE version. This includes me.
I did a clean install which means adaware was never on my system and hence it should have got activated as they are saying but it did not.
Update: I was able to activate it after I uninstalled it and installed again. Here is the trick : You must be connected to Internet when you install it first time and reboot otherwise it wont get activated if your internet connection is not working on first reboot.
