My monitor is reporting that Elelemental is "out of range".

I've had this happen a couple of times before and it isn't so hard to fix. However, after playing with the Default file in the Data folder (which is, I assume the right one to fiddle with) I get no where. It seems to ignore my request for 800x600 windows or windowed mode.

Does anyone have a solution?

EDIT: Found out that 1024x768 is the minimum resolution and tried to set it at that, but it still says it is out of range. On a side note, I was playing the beta without any problems, so this is new.
