What other games did you ever install/uninstall on that particular system?
It doesn't really 'Ring Any Bells' with me, but it could sound like a copy
Also, clean your disc - clean the drive - if your CD is (are?) IDE/ATA, try
swapping or re-seat the flat-cables - if HD is SATA, definitly re-seat the
SATA cables and/or buy a set of better quality.
Is this isolated to 'AOM'? What is AOM, anyhow?
Is this a new PC - what OS?
