Just acquired Battle for Middle earth, however may have dropped a clanger. On the back its states it requires a DVD ROM, however my laptop only 18 months old has a CD/DVD drive, and won't recognise the disc. It did recognise and play the LOTHR game however. The disc is fine because I have a desktop with a plextor 708a in it that recognises the disc. Anyway I can get this to play on the laptop, or do I need to get a new DVD drive.
