CD/DVD Drive Not Working

First of all I have Windows Media Edition
Suddenly my drives stopped working

Device manager is telling me:
Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

I tried to delete the "upperfilters" and "lowerfilters"
Also I have tried uninstalling and reinstalling the drives
and finally updating the drives

And of course none of them worked

Please help!...

 

I had similar probs - my registry was currupt too see here: http://forums.majorgeeks.com/showthread.php?t=177676. Try this it worked for me.

1) Backup registry by Creating restore point.

2) Download this and double click it. allow it etc.

Forgot to say you'll need to reboot after.

 

No it didn't work.
The registry entries are gone but the drives do not work...
