Question: I have just taken delivery of my LR5 disc. I had already downloaded the trial version. I just tried entering the serial number from my hard copy to authorise my downloaded trial version and it did not recognise the serial number. So, I loaded the hard copy, and the instructions said that it would just overwrite the downloaded version. And again it will not recognise my serial number! I am not wanting to uninstall the trial version as I have already got quite a lot of personal preferences entered etc. Help please. I am on a macbook pro with latest OS
