I use the code that I found it on YouTube include everywhere you can find it to use the code when you take off the internet wire. Until few days ago, it allow me to use it without enter the code. I don't know why because that code is already used by owner of that code. I don't see why not to use it. I start recorded for play Undertale and all the suddenly, I can see my webcam box on Camtasia Recorder start glitch up like you play video game and some time game start glitch make screen go mess up for while then back to normal. Then all the suddenly, the audio start early that my Webcam didn't pick up my laugh action. How can I fix this webcam glitch when I use Camtasia Recorder?
