Okay my os is windows 7 professional, ram is 8gb my cpu is an AMD am4 5300 apu radeon hd 3.4 ghrtz oh and my graphics card is an ati radeon 5400 with 1 gb of ram on it. So I took a lot at the graphics page and as it turns out I didn't have direct x 11 installed which is funny because I was able to play elsword without it earlier I think. So I just went ahead and installed it, also it says that open gl can't be down loaded because its an integrated thing apparently. Which i think is dumb they shou ld really allow you to download it, so I looked into add/remove programs and it not even there but open al is there but idk if that'll help or not though.
