Crashing every time move someone to another channel

My hubby and I both have Teamspeak on out computers. I am Server Admin and he is Admin. Starting yesterday, every time he tried to move someone into another channel his TS crashes. We both have the same computer setup, we are both on Windows 7 64bit, and we both have Teamspeak 3 (3.0.17). Any help?
