Webcam stops working after a few minutes

Hi everyone,

I'm having some trouble with the live video stream using Adobe Connect and I wonder if anyone can offer any advice.

I´m a trainer using Adobe Connect giving classes. Everything was fine until I got a new laptop.

This is what happens before the problem occurs: I log in as a participant an will be designated as a presenter for the meeting by the host. I start the meeting. My webcam turns on. I see myself, everythings´  fine. I click „record meeting“ and start recording.

Now this is the problem: After few minutes the webcam freezes. If I stop and restart the camera, the camera showes up a black screen.

Hardware, Software, desktop configuration:

• Notebook: HP Probook
• Operating System: Windows 8.1, 64bit
• Webcam: Microsoft LifeCam HD-3000 (Webcam workes just fine with old laptop)
• Browser: Firefox 28.0

I also had some serious problems last Thursday affecting audio and video. But I suppose it had been this: http://forums.adobe.com/message/6228702#6228702

If anyone has any suggestions, I'd really appreciate it.

Thanks!!!
