Problem with demo savings

[Hielario]

I can't save my playings. In the options display, I click in "New save game" and then I click in "save": The button moves but nothing happens. And the button "Load" doesn't reaction.

Is this a mistake by my computer? Or it is a demo's feature?
Please, answer me, I can't playing the demo in one time only .

Excuse my English.

Sorry, the save option in the demo is disabled. This is because the games saved by the demo would not be compatible with the full game.
