You may want to repost in the GCII forum instead of Object Desktop.........
Possible causes......
1. GCII is a DVD not a CD (I don't know, I'm just stating possibilities)
2. GCII is a newer format CD than your hardware supports.
3. GCII CD has got some schmutz on the bottom and it can't be read until you clean it.
4. GCII CD is bad and needs to be replaced.
I'm sure there are other possilities but I'd check these 4 for sure. 
By the way....the capital letters (yelling) in your post title is likely the reason it took 10 hours vs. 10 minutes to get a reply.
