DVD player is working but not burner

hi.. i need someone to help me..

i always use nero to burn anything i needed before and there were no problems. not until one day when i tried to burn some data into a disc, i found that nero did not detect my burner driver anymore. the only thing in there is just imaging recorder i guess.. i tried to uninstall and reinstall but the same problem persist. Good news is, the dvd player is still working excellently. it's just the burner driver. how can i solve this problem?
