I have down loaded the update for LR which should be LR CC (2015) but although the download says it has done it I can't get the program to load. I can see it in the Adobe Creative Cloud and it will let me into some tutorials but the program will not run. The previous version 5.7.1 still works and has been unchanged. What am I missing?
go to CC, logout (not exit)
then try LR again
It worked! Thanks but I have never had to do that before - every upgrade has just loaded and away it went. We live and learn. Thanks again.
