I purchased Lightroom 4 from the Mac App Store in May 2013 and would like to upgrade to Lightroom 5, but it doesn't seem possible. Why is this/how can I update? Thank you!
You can purchase the upgrade here: Products
Make sure you retain your Lightroom 4 serial number, as you will need it to get Lightroom 5 running (you will need your LR 5 serial number too, that is e-mailed to you once the purchase is completed)
