The load button (load campaign as opposed to save) no longer shows all the second series of missions. It goes through all the first Roman, Egyptian and Asian missions up to
8. I Asian Campaign
then
2.II Roman Campaign
4.II Roman
7
8
and similarly for the subsequent Egyptian, Asian and Amazon missions

How can I get back these missing mission, I have tried repair and uninstalling and reinstalling but they are still missing?

I believe they were there when I first installed, does everybody else have a 1.II. Roman campaign?
