Won't import pics from laptop

Monument has simply stopped uploading pics, unless I do them one at a time.  I have thousands of pics!   And they won't display on my TV, hooked up via HDMI cable. I bought it for all the reasons it is marketed, but it simply does not work.  Support is trying to work with me, but really, nothing is happening.  I'm getting ready to return it to the retailer unless someone can help me to get it to work.
