That's an interesting error - looks like the problem was specifically with this download: 1487102400000.html.gz
You can try deleting that file or all the XXXXXXXX.html.gz files from the cache folder and see if it gets better data.
I am still up and running on my system - so I don't believe there was a change to the Screener site that would have broken it.
I should probably look at adding a "delete cache" function in the program so when there are errors it can run a clena download.
Let me know if clearing the cache file works.
