Arma 2 free very dark on low settings

[retrolinkx]

I recently downloaded arma 2 free and on the lowest settings possible it is almost impossible to see anything because it is too dark. I am unable to increase the settings because my computer is incredibly weak.

This is what it looks like

however when it is paused it looks good.

is there any way for me to make it look more like it does when it is paused?

also i tried increasing the post processing effect but that makes it worse:

Whats the ingame time (keep 'o' pressed to watch watch ^^) ? and what are your video settings? could you make a screenshot of them?
I don't know if you can use the Editor in the free version, but if you can, use it to set the time to 12:00 and try it there, because it is also possible to set different filters per script (with this filters you can get a better atmosphere for cold/hot regions, so a filter for cold region could make the screen dark too, and those filters aren't active while in pause menu)

Thank you, it worked, this thread can be locked if it serves no more purpose.
