The only gamestudio version that ever was cracked, meaning unlocked to a working Pro, was an A6.2 beta version.

A Russian hacker group attempted in 2007 and 2008 to crack A7. They reported success several times and published many "cracked" versions on warez websites. None of those cracks did really work. They apparently gave up after a year, at least we did not hear about them again.

Of course, anything can be cracked, but this would require a real programmer, and he had to invest weeks of serious effort due to the various anti-crack mechanisms implemented in 2008 against those Russian hackers. As no one has seriously attempted this so far as to our knowledge, a cracked Gamestudio version is not to be expected.
