ST10+ video start/stop button not functioning

I just recently acquired my Q500 (within the last two weeks). I'm trying to use the video start/stop button on the ST10+ controller, but it is not responding. Any suggestions?

 

Nothing at all. Everything else works fine, even the individual photo capture.

I tested via the Hardware Monitor and no response. The button doesn't even click.

 

ISSUE RESOLVED

I grabbed the button with needle-nose pliers and pulled it out a bit and everything's good to go!
