Ldw411s:updated firmware but it wont burn Cd

I ve bought(I don t remember when)my liteon ldw411s.It could burn DVD- and +R,and also all CD formats.But at the beginning it didn t burn DVD-R.So,when liteon released fs0k,I updated.Finally I was be able to burn DVD-R but…surprise:I wasn t able to burn CD(any type)anymore…I returned to older firmware version,but it was the same thing…Could someone help me?
