Record button freeze whole project

Hi, I'm new in Character Animator and I have no idea what I did wrong... yesterday I can recording puppet movements, editing it, everything. Today, I want to record new scene but when I click record button, puppet freeze, arm don't want to move, non reaction. Also timeline freeze. In camera&microphone window everything looks good and when I'm not recording puppet works fine, I can do everything, but after countdown to recording - nothing work. I tried reinstalling programm but still have that problem. Any ideas what can I do?
