There's a cracked version made by some random person on Youtube: https://www.youtube.com/watch?v=esLHY7FeRq8 no key required. I tried it and didn't get a virus so I assume its legit
also a direct link to the download http://www.mediafire.com/file/al5nq32m9bllcqw/Real_Space_3_OFFICAL_REDISTRIBUTION.rar/file
Wait, if the key doesn't even work, and this site offers no support, shouldn't this thing just be removed altogether?
He's right, the registration key it comes with doesn't work.
Key doesn't work.
