Endnote crashing with mac 10.13.2

Hi,

I just downloaded endnote. But first it crashed everytime I opened endnote.

But now it just don’t react when I try to import my references - I just export as RIS from the library and drag from the downloads to the library in Endnote.

Can someone help me? 

I highly recommend to you contact support directly tomorrow.
