Vista 64 bit - Drive letter "@"

[Kuurus]

I am running Vista 64-bit SP1 and Microstudio 4.006. All of my CD/DVD drives show as drive letter "@:"


I have removed the drives and cdromdrivers in Vista Device manager, rebooted and still come up with the same problem. When the DVD/CD-Rom drives come up they install with "C:\Windows\system32\DRIVERS\cdrom.sys" as the driver (I have a Pioneer DVD-RW DVR-109 and a Plextor PX-712UF drive). Both show as drive letter "@:" instead of their correct drive letter mapping.
