I bought a USB Flash Drive, and installed the software onto my computer. When i did that, It erased my CD-RW Drive and CD-ROM Drive. My Flash Drive has a letter of D: the same thing as my CD-ROM drive. When i went into Windows Media Player, It said "Detected No CD-RW Drive"? How can i re-install my drive??? Please Help! I already tried restoring the computer, reinstalling the drive and trying to delete the USB Flash Drive Disk!??
