Why is this an issue? This is the only program I have ever used where the program itself will not allow you to save. I have over 78 GB of space on my hard drive and 3.40 GB Installed RAM. Why is this an issue I ask again. I do all this work in Lightroom 5.7.1 and can't save or export. No one has a solution and none of the troubleshooting works. Why do people continue to use this?
Have tried closing the other program while exporting or saving a file from Lightroom.
