It's small because it's the 800x600 windowed resolution.
Make sure you installed the game first, then ran the Update.exe provided on the Downloads page of LastCo.net
If that was completed, try to restart. it looks like you have Vista... or maybe Windows7 not sure. You got a weird setup there on the bottom right. I do recognize a game or 2.... S4... don't know what HON, maybe SoldierFront.... naruto... oh you sneaky boy... lol and Aion?
Looking for the settings file for you.
OH make sure you run the Launcher.exe first to load the game up :)
I can't find the settings file. It used to be this ini file that you could config if you wanted different resolution or windowed/full screen :/
