Urgent help needed nec2510a

For some reason i tried burning a dvd today and i noticed that my dvd drive isnt recognized as a recordable device anymore.

In nero i lost the option of burning dvds and when i look at my computer the dvd drive is shown as a cd-rom drive.

I can sitll play dvds fine, but i cannot burn any, because all the options from nero are blacked out.

Someone help, i dont know what went wrong.

nvm problemed solved.
