Day's Eye Error

So.....ummmmm I am new to this site and I need help. So I am assuming people are familar with "Day's Eye". I wanted to play it for a while but I was younger at the time and didn't have a PC so I couldn't get it and recently I found the OP on youtube and I was like "It is my chance too play it" So I downloaded it from this site and then when I started to game, This popped up. I know that this game is a few years old so it is hard to get because It is underrated but can someone help me if possible? If this can't be fix then is there a different way to get it? Thanks in advance!
