After asking to use DVD drive on my PC and getting a confirmation (which takes a long time) on my PC I get a Disk Picture in my Finder on my macbook air. When I click to open the CD, it says the original file of iWork cannot be found. However it is the original because I bought it at the store where I bought my Mac Air at. What is the problem? Edit: It is working now, it took like 10 minutes though after i clicked get original, as i only had an alias?
