One thing you can do is to remove the security patch installed for Tradestation to work again. Go to "settings -> update&security -> update history -> uninstall updates. Click on Security update under Microsft windows section.  It will reboot and then after that Tradestation will work again. Remember it will work windows install the patch again overnight. I have been doing this everyday to make it work. If you want to  permanently remove the automatic updates, you can google and figure that step by step actions to do so.
