I got a new dell laptop with Vista and both hate and love it!! I love the fact that if I spill coffee in it or break Lcd they will be here within 48 hrs to repair free for 3 years (already have) and love some new extras but hate that it won't run a lot of my prior software

What to do? I installed something it don't like and my Cdrw drive vanished?? I have done everything I know to get it back but so far, nope:
