Error- Windows Movie Maker - Class Not Registered

I am using Windows Movie Maker and after SP2 update it stopped movie maker from downloading from firewire to my sony cam. It was working fine previously. When plugging in the firewire, then Sony is recognized. Movie Maker suggest upgrading the Ati Radeon 9200 driver and I did that but it made no difference. The movie maker connected to the Firewire on my Sony digital cam no longer downloads. The wizard step where I expect to see the video and controls that shows - Error- Windows Movie Maker - Class Not Registered

Please help me.

Can you try to execute the below line by going to Start and then Run and type the below

regsvr32 %windir%\system32\qdv.dll
