i just got my macbook 4 days ago. the other day my dad was using it to install the windows office thing and he put the cd in and it worked fine. the next day i was getting ready to play a game, and i tried putting the cd in and it wouldnt take the cd. i pushed the cd almost all the way in and it made a weird kind of noise similar to when a cassette player eats a tape, and it ejected the cd. i shut my computer off and waited until the next day. then i tried it the next day and it did the same thing, and now you cant even put the cd in halfway. it feels like theres something blocking it on the right side. does anyone have an idea of what the problem could be? it hasnt been dropped, nothing other than the first cd has been put in the drive, i've tried 3 different cds, all which have been brand new, and the cd is the standard size.
