My operating system ist MS Vista Ultimate + SP1 (German)

My problem is I cant record any file over the "Microsoft Internet Explorer [7.0.6001.18000]"

My steps:

1. I delete all temorary Internet Files
2. I start the Replay Media Catcher
3. I surf to a flash-Video-Site like "http://www.youtube.com/"
4. I start a video.
5. I jump to the window of Replay Media Catcher and the window is emtpty!!!

I start the program as Administrator
I deactivate the User-Control.
I uninstall and reinstall the Programm.
I restart my Operating System.

What is my mistake???

With Firefox I have no Problems!!!
Only the Microsoft Internet Explorer [7.0.6001.18000] will record nothing!!!

Thank you!
