I upgraded my Windows 7 to Windows 8 RTM but the DVD player now refuses to work. It's a MATSHITA BD-CMB UJ141EF drive in a Toshiba laptop. It's showing a yellow exclamation mark in Device Manager which is reporting the following message "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)". Any idea how to fix it?
