How do you open games with the Easy CD creator?

Ya, see I have a shitload of programs and games I've downloaded that you have to open with thie Easy CD Creator thing. How do I open the damn game? I've tried using a CD but it just keeps telling me to put a CD in the tray when there already is one. Thanks in advance for any help.

I am confused, when you mean open the cd, do you mean "explore" the cd? And are these "CD's" you are downloading some sort of CD IMage format? (ISO< CDI, BIN)
