no disk-exception processing message 0xc0000013

All of a sudden, every time I open either my DVD drive or my DVRW drive to
remove a CD or DVD, I get an error saying no disk and "exception processing
message 0xc0000013 parameters 0x759f023c 0x87f51935 0x759f023c 0x759f023c."
I believe the only two things I did before this started happening was to
update Itunes/Quicktime and update Corel PSP X2.
The drives both seem to work ok so I'm not sure why I'm getting this
message.
It gives me 3 options: Cancel, try again, or continue. When I pick one of
those options, nothing happens the first time around.
I am using a Vista 32 bit computer.
