Hi Buzz, and welcome!
I admit I have been having intermittent trouble over the past week with Supertote in all versions of RDSS - for example, freezing the computer as you describe. I've been traveling though, so I wondered if it was simply the network connection I was using, e.g. yesterday at Del Mar, and last weekend at Woodbine. OR - as you mention, if it had something to do with last weeks major Win10 update? The fact that it doesn't happen all the time makes it a little hard to debug - but I will keep on it while I'm out here in California.
However, today for example, at least Saratoga seems to be working fine.
Usually the one definitive way to know if Supertote should be flowing in RDSS, is simply to open Brisnet Supertote in your web browser and look there at the tote feed for your track. If tote data is flowing in Supertote in your browser, and you have connected RDSS to Supertote by the usual method, then tote data will flow into RDSS. If no tote data in Supertote in your browser, then also no tote in RDSS.
What track are you following right now?
