How many discs does this EQ2 you have, have? If it's 10, you have the CD-ROM edition, and then we'll go from there. If it's 2, you have the DVD-Edition, and that would explain why it doesnt read on CD players :)
EDIT - And by the way, if you intend on playing EQ2, you'll have to buy your own boxed copy, as yes, the game does require an account key to create an account and play. But you can still install it with an already used copy.
