I love this game, but a few months ago I changed a couple files in my Ubuntu 13.10 system while trying to fix another game, and now when I try to load Factorio... the images and the backgrounds of the text inputs and boxes dont seem to load properly.
My admission of guilt is that I'm not very experienced with Ubuntu or Linux, and I don't remember what the files were any more... but they were part of running a Steam account game, and now there seems to be some conflict T____T
here's an example of the game when it fisrt starts a new map:

I know the problem isnt with Factorio, but I'm not sure where else to go to fix this, and I'm hoping you'll have seen this problem before?
thanks,
