Latest Photolab update freezes

Just trying a download on windows 10 now - it’s stuck on 48.0/412 MB. This is the first download of PL where I’ve ever had a problem. I tried Pause / Resume over a dozen times with no success. Then I cancelled the download and started a new one via “Check for Updates” in PL4 - this got a bit further (75MB) then paused, then reported Failed - Network error. I resumed this download and it got further (!94MB) then hung again. I cancelled the download for a second time then restarted a new one again via PL4 - this time it’s hung at 66MB. I guess I’ll give up for now and try again later.
