We have already had one player who has had issues with the latest Windows 10 update, so lets start there. A DXDIAG output might be helpful.
A description of what you were doing when the game appears to lockup might help.
When you say lockup, what makes you think the computer was locked up? Did Ctrl-Alt-Del not bring up the Task Manager?
We are not in the office on the weekends and our office closes Friday at 5:00pm CST.
