Do not have all services for MS SQL to run setup...

I installed the april version but it does not seem to have all the services...
Could anyone give some help... I have a DVD of MS SQL but it just will not stay in my DVD drive heh it just pops right back out... More info? My OS is WindowsSvr2003 Enterprice (Downloaded) and I used to have Windows XP Home but when my computer stoped working I had to delete all portions and format my hard drive clean and install an old version of windows so I could download WindowsSvr2003 thats all well that stuff was useless
