No rush to fix it. You are correct, it was the lack of a save game. I started a new game, then went into the settings, and could play. Including going to full screen. However, the small window remained prior to that, and i had to squint through the tutorial screens. Let me know if you have any questions, or would like any diagnostics, ill be glad to help.
Hi. Glad to hear that the workaround... worked. About the screen size issue.... the minimum resolution that the game runs at is 1024x600, and it is also the default resolution. Unless your monitor has a really high resolution, I'm not sure what's up. Have you been able to go into settings and pick a higher video resolution setting and press the tick button to adjust it? Failing that, are you able to go into FXDcustomise.ini and set window width to "1600" and height to "900", or "1920" and "1080" for example? It seems very unusual. Does your monitor have a very high resolution compared to the physical screen size, like a 13" 1440p display? I'm really baffled.
