Video Demo - Crashes Captivate

Thanks for the suggestion. We tried this with the Adobe technician yesterday. Still no luck.

The technicians I've had working on my PC have been great. However, I'm at a loss for words when it comes to the way the communication works in the support. An agent tells me they're going to look into my case, and they disappear for hours. The next agent tells me a different team is handling my case. That team seems to have gone home by then. I get an email saying they are still waiting to hear from me, but it seems to be impossible to get hold of the team. 

I was told by a technician that they need to look into the problem I have. Here are some of the things we've tried so far:
- tried resetting preferences of Captivate
- tried to change the video demo folder location
- tried to stop third party apps which might conflict with Captivate
- technician says I don't have admin rights on my PC which I do, it's mine and I'm the only user. This was confusing. Anyway, we did the following: we created a new user on my computer with full admin rights, and tried reinstalling etc.
- in the end, the technician suspected there was something wrong with my video drivers. Checking them was one of the last things he did before he said it needs looking into more.
- I informed the technician that the video demo worked the first time I used it. The following day I tried it with a new webcam, and I was never able to launch it then nor after that.

I hope this gives someone else tips on what to do if you have the same problem.
