i can't run reason 5 on os x Mavericks, why not if i can run this app on past version?

I hope that every update is to be better software, but i'm thinking about this. =(

On OS X 10.8.5 i can run the propellerhead reason 5 the easy way, but before i update my software this "crash" and don't work more.

Anyone knows the reason why not works this app?

Thank's

PDT: Is only this app, 'cuz the others apps (Logic & Ableton) works fine.
