Game crashes at start

So I can't get to run my RO2 for months since I tried to install this graphic enhancement mod:click!



I don't really know what I have done wrong but I just can't get the game to work again, redownloading and validating gamefiles didn't help at all. I also don't get how to use those "batch" files in the downloadfolder and feel completely helpless with the readme -_-



Don't want to miss the MG42, help me guys!
