Well, again, with this build i can't upgrade my 4.8 to 5, it stays where the others stays. It can't transfer the license of my 4.8. But this time it can start and no freezes, this is in win xp sp3, but in 7 i just have tried clean install of version 5 free, and it's better than previous builds. I will stay with 5 free for one month, at least, when another 2 builds come out, and i can test again the upgrade from 4.8 to 5.
This is a great build!
