To the best of my knowledge, no - but I'll have to check when I get home from work.

Hi Iceman
The cheat worked after a fashion, I used the campaign cheat, but I have to unlock every time I want to play a mission - so I don't get the whole storyline, branches and all - but don't sweat it, I'm playing the very last mission right now, so there is no need to do anything more

Hi Iceman,
That's just what I did - highlighted "Win" on the campaign screen, left shift + keyp minus, entered "campaign", enter. Selected the first mission, and selected "revert".

After finishing the mission, the campaign screen was back to its previous state: "win" campaign was not selectable.

it does look like a read/write permission issue
