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?
Could you please specify what exactly happens with Lightroom 5 on your Mac Yosemite?
Did you purchase the retail version of Lightroom or Cloud?
Send me the serial key via Private Message option, so that i can validate that for you.
Thanks, I'll do that when I get home.
Hi, sorry, but how do you access the Private Message option?
