V5.0.8 - 64bits Windows 7


I just had a computer crash, never seen anything like this, pretty mutch the whole thing shutted down after a while, sending me messages about "not enough memory..." ( I had only google chrome open ) and things like that before going into black screen.
I was begining to paint something on Artrage5, this happend right when I loaded my save ( a very tiny painting ) and started using my pen. Artrage sent me a message saying I will lose my settings because it couldn't save them.

So after a computer restart, I lost all settings indeed. Is there a way to find the old settings file and restore it ? If not, can I back up the new one ?
