Can no longer save XCOM Files

[Scrogg]

I downloaded XCOM Files a couple of weeks ago and I've been loving it so far, but this evening when I loaded it up I was confronted with this error (attached) every time I try to save. Autosaves are the same - the automatic battlescape save is how I initially realised there was an issue.

Does anyone have any idea what is causing this and how to fix it? Much appreciated.

Move `user` folder from program file folder as you try write on protected folder.

Thanks - that didn't work but it did make me rethink and I ran the game as administrator and I could save again! So thanks for making me think of that. I don't know why I didn't think of it before, to be honest.
