Most likely the large ribbon cable that goes from the motherboard to the drive board on the disc drive is bad. There's a good chance that the little ears on each side of the ends were torn off or broken when you removed it. This is a very common problem. The other thing that it may be is the small metal tab that's on the bottom case. If that small metal piece does not make contact with the copper pad on the disc drive board then you won't be able to eject a disc. Since it won't take a disc in that means that there is a problem somewhere else too but you may want to check that metal tab as well. I hope this helps.
