Hi Folks, I bought my wife a MacBook Air (11") for xmas, and as she loves the 'Sims' games, she's trying to run it on the MBA (I will point out however that the Sims games are not my cup of tea!). She has successfully installed the game by sharing the DVD drive on the iMac, and gone on to download any updates successfully. However, she can't seem to get it to run. The game obviously requires the DVD in the drive to play, so she has again put that in the iMac and shared it. However, when she tries to play it gives a 'disc not authorised' error and asks to insert the 'World Expansions Game Disc' (she has tried with both the expansion disc and the original game disc, same error on both). I've had a brief look at it myself, and I'm stumped. I've found a few threads suggesting others are doing it this way without a problem. Any pointers much appreciated!
