Okay so when I try to change the quality of the game (I try to change it to highest 1012x1210 I think?) It turns the game sideways. I have a fast computer and high quality worked before but the game started lagging so I turned the quality down. Later when I wanted to change it back it turned the game sideways. If you know how to fix this please tell me. Thanks!
First thought would be to just have you turn your monitor, but that's not good. Assuming this isn't specific to the game - I found the following from another "sideways soul":
Q. I attempted to press CTRL + ALT + DELETE to bring up the task menu but must have inadvertently pressed a different key combination. Now the display on the screen is horizontal (from left to right) rather than vertical (top to bottom).
A. Some video cards support the rotation of the image on your computer screen. You'd use this if you a monitor that can also rotate. Web designers and artists use this, as an example, to check long pages.
It would appear that you managed to press CTRL + ALT + Left Arrow by accident, to correct this problem simply click CTRL + ALT + Up Arrow.
Please let me know if this doesn't resolve your issue or it's specific to the game and no other program.
