HP/Compaq :: HP Dv7 Remote Control Won't Work After Format

When I first got my HP DV7-1285dx with Vista (64) the remote control that came with it was working fine. I upgraded to the Windows 7 beta when it came out (I didn't do a clean install) and the remote was still working and kept working throughout the several beta upgrades I did later (to newer beta versions). However when the Windows 7 RC was released earlier this week I decided to do a clean install so I backed up the important drivers and files and did a clean Windows 7 install. After that my HP remote simply stopped working, the laptop won't respond to it at all (not in Media Center and not in anything else). I was able to reinstall all the drivers (from the backup) except for one which shows as "Unknown driver" in Device Manager, and when I do a driver update and point Windows to the folder including my backed up drivers, it does recognize the device as the "HP Mobile Data Protection Sensor" but says it encountered an error installing the driver software since it "couldn't find the file specified."

I don't know if this "Unknown driver" is in anyway connected to the Remote Control problem. I have no other problems showing in device manager by the way.

Also in an unrelated matter, I am trying to reinstall the MediaSmart software the came with the laptop. I downloaded the packages from the HP website but they won't install (since they're only update packages and not standalone installers I guess) so is there any way to reinstall the MediaSmart software from the recovery discs/partition?
