If you're on XBOX, then I grabbed something, here:

FYI having an "older" model Xbox has nothing to do with JE not running, atleast not in the sense that the disk itself can't be read due to it's manufacture date. I've had an Xbox since it came out, and it can run any Xbox game I plop into it.

The problem, I would tend to think, would actually be with the CD itself. I would suggest checking for scratches, dirty, and making sure that your Xbox is kept clean and dirty free. If you notice scratches and you don't own a repair kit, I would suggest stopping by your local EBGames and asking them to clean and fix it up.

Also, making sure your Xbox is kept clean is a sure fire way to ensure that all your games run smoothly.
If it's for PC, I found this for a game called Theme Park World. But it might work for any PC game, here:

Try placing the CD in another CDROM device and running the game
We have found that the game works best by placing the game in the device with the lowest drive letter. For example a drive D will have priority over a drive H.
Try placing an audio CD in the other drive(s)
Uninstall & Reinstall
