when i click import, it says, LIghtroom not responding.....I can't import photos. I have to open and close lightroom several times, sometimes it doesn't work for hours.
If you are using Lightroom 6, then try turn off the Graphics Processor from Lightroom preferences.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Let us know if that helps.
