HL-DT-ST DVDRAM GSA-T50F Driver

my dvd/cd drive isnt working on my gateway fx seince updateing to windows 7 beta. i may have to wate till they update the driver but im wondering if anyone has a trick to get it to work. this is what the drivor error says.

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)

it has 2 drivers in the detailed drivers box one is windows verified the other is not and i cannot seem to delete the one that isnt w/o deleting them both and last time i tryed that it crashed windows and i got the all famose blue screen of much sadness.

any suggestions? i tryed updateing and uninstalling tryed doing scans on it and everything it just dosnt like the new windows now it seems.
