windows 7 does not recognize hf20 connection!
 

I sucessfully installed the bundled software that comes with my hf20 on Windows 7, but when connecting my camcorder to the computer, the software that enables the hf20 to download via USB failed to install. So the computer does not recognize the connection, and I cannot download the video files.
Has anyone else had this problem? I can successfully connect my hf20 to 2 Vista computers. Is this a Windows 7 problem? Is there a patch I can download to fix this issue?

Thanks
