Fangking Omega: In the script SpriteResizer, you have to modify lines 11 and 12. The Resolution* script only handles centering the player on screen, as far as I can make out.
Phoenixprime (and the tons of others who get the same error): Try adding this line directly above the line causing the problem (line 1120):
I'm sure there's a better way, but at least it prevents the error.
Zephyr Gale: The line you're getting the error on refers to the Audio.dll file. Check if you have this file first; if you do, then specify more about when the error happens.
And usually, the problem lies with the first line on the list - the others are the lines that line refers to, which may contain an error instead. It's usually best to fix the first line before attempting anything with the rest. Hope I helped!
EDIT: This is what happens when you change the resolution without changing your graphics.
