Can't re-write any disks

Ok I am running NERO and I was going to erase my re-writeable disk, but now it says its read only. Ok, so I tried Alcohol 120%, it too says its not re-writeable.

So I tried all my other re-writeable disks, and now they are all read only.

WTF is going on?

Found it, some stupid option in Alcohol 120% that marks ANY disk you put into the DVD tray as a CD-rom
