    Not able to user LR5 on new Mac Pro with Yosemite on it?


      Hi I had LR 3 on a Sony Vaio, I bought a Mac Book Pro (OS X Yosemite), so put LR 3 on that, however I received "an error occurred when attempting to change modules" message. I then upgraded to LR 5 on both machines, it seems to work well on the Vaio but not on the Mac. The Mac also doesn't retain the Ser No: details. What do I need to get it working on the Mac?
