hello, I don't know why but the record and preview buttons are not clickable in the photo, and I can't even select my hands.

You mean that you can't select the Hand option for the character? You would need to enable that first before Preview and Record become available.

yes i can't select hand. The character is a cc3+ import of character creator. The first installation i can to do animation hand, after i reinstallated iclone and i have this problem.

Now when i click on the motion live doesn't show the windows of motion live. I try to reinstall motion live and leap motion but doesn't resolve my problem.
