Always helps to give us details, such as what version of Lightroom, where you are importing from, describe exactly and in great detail what happens, quote the exact complete unedited error message. Thanks.
Some things to try:
I am using latest lightroom cc 2015.1.1. with camera raw 9.1.1. I am importing from a folder from my desktop, its says import files at their current location on the top left hand corner and in the middle of the screen says importing files, but nothing is happening
