Lightroom on PC used to work fine. The problem started when importing photos and a few videos from Sony A6000. Import process hung at the beginning. Cancelled it, restarted Lightroom and tried it again. Still hung. removing the video files worked around the problem.
Because of a problem of Adobe Cloud, my lightroom stopped upgrading for a number of months. is this problem fixed in the latest release? what version of lightroom has the fix? This is a very annoying problem. imagine if there are a number of video files in each folder, copying them out and deleting them on the card would be a lot of work.
Could you please update to the latest version CC 2015.5.1 directly from Keeping Lightroom Up-to-Date
