I'm not sure, but probably. Anyhow, the problem has been resolved. I re-installed the game until BOTH the original game and the update worked properly. This took quite a few attempts. Sometimes the problem occurred when I just installed the original game. I would install the update to see if it would fix that, but no such luck. I kept re-installing the game until the command posture icons were displayed in the original version and then upgraded. Thankfully, that worked.
