Long Game

[High Chunker Greens]

I am having trouble trying to get the game to last longer by adding in lots of turns. I know how to change the file so ther are more turns, but when I try to save it, an error message pops up telling me that the path and file name are not correct and cannot create it. Does anyone know what the problem is?

The file is write protected. Right-click it, choose 'properties' and uncheck the tickbox 'read-only'. Click Apply and OK. Save your file normally.
