I can't burn anything with my DVD/CD-ROM

I can't seem to burn anything with my laptop.

I have installed Cyberlink Power2Go and every time I open the program, it says "no burner is currently available or you don't have rights to access the burner". I have read a similar thread saying that in order to solve this problem, I'd have to delete the upper and lower filters. The problem is I don't have those in my regedit so that does not seem to be the problem.

i've already uninstalled all the other burning softwares.. the only software i have now is cyberlink's power2go..

if i insert a blank CD, it won't detect it.. it would say 'please enter a disc into drive E'.

My OS is microsoft windows vista home premium service pack 1.

as i've said, every time i open the power2go software, it would say that No burner is currently available or you don't have rights to access the burner and i can't burn anything after that.

here's my optical drive properties.. thanks..
