Jump onto steam. Bring up your game list. Drop down to Starbound. Open up properties, click to the update tab. Select keep this game up to date, and you're good to go. Edit: I would advise checking the beta tab and selecting opting out of more beta then beta. It will be very unstable when they push those compared to the regular "beta" build.. but if you have to have the most up to date? You can opt into it for when they push more experimental updates out the door.
You may have a mod that is conflicting with it. But gonestly, how you expect anyone to help with such little information is beyond me.
Soo... are you going to provide any information then? Your log, for example? Sayign "It doesnt work, help me!" doesnt tell us squat.
