installing dvd burner in acer notebook

I bought a dvd burner (samsung) to replace the cdr/dvd combo drive in my ........acer aspire 3002 lci.
I seem to be having a little trouble......i removed the screw in the bottom of notebook that allows the optical drive to slide out.....but it does not want to seem to budge.....i applied a fair amount of pressure on it but it does not want to slide out.

Any help would be great.
thanks

Did you check the acer website? When I added some ram to my moms laptop they had a whole section of step by step tutorials with pictures to help you along. You may have to remove something else first to get it out.
