Windows 7 won't run my DVD drive

I bought a new LG DVD/RW SATA drive recently and it worked fine in Vista. I upgraded to Windows 7, but it won't work. Device manager shows the following error:

HL-DT-ST DVD-RAM GH22NS30 ATA Device (basically an LG drive)

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

Any idea of the cause or possible solution? I have tried uninstalling and re-detecting devices.

 

I am having the exact same problem and yes it is the 64bit version of Windows 7.

 

Check out this TechNet article.

 

Try to reinstall the drivers by using compatibility mode and selecting "windows Vista ".
