Liteon problem

I bought a LITE-ON Cd rewriter 24x10x40 a few months ago after reading the review on CD freaks. I am very pleased with it, but recently, when I insert a blank CD it starts making noise and just opens after a while. It takes me 5 trials before I actually can burn something on the CD.
I am using the last version of Nero and I have tried lots of different media. I heard about this “laser calibraton” problem. Does anyone thinks that it might be the problem? Can somebody help me. please! Thanks a lot in advance.

Maybe a new firmware will help…

or here

thanks a lot. I will try that…
