Feral Heart

Hi, I have a mid-2011 iMac with the OS of 10.12.6 and I was wondering if it would be possible to run FeralHeart on this model. The Graphics Card is AMD Radeon 6750M 512 MB, a Memory of 12 GB 1333 MHz DDR3 and a 2.5 GHz Intel Core i5 Processor. I believe I read somewhere that the game was released somewhere around 2011, so I thought there would be no problem downloading the game on this computer. I just wanted to be sure about the game's actual system requirements though, as I am struggling to find an answer to that question on the internet. Thanks ^^

I began to play on feral heart a few days ago, not expecting anything unusual. The black screen before the two loading pictures came up, and before they even came up, the sign 'FeralHeart.exe has stopped working' appeared. I have seen this sign before and simply just restarted and it never came up again, so I did the same here. But surprisingly it came up again a second time, and even a third time. I can see it is just going to keep doing this. It has been like that for around over a week now, and I'm starting to get concerned as I have heard you may have to 'reinstall' feral heart. For a start I don't even see how to reinstall FH, but what worries me even more is the fact I may lose all my data like my characters, maps, and everything that I ever made in this game including friends. If you do have to reinstall this game, is there any way I can keep all my data? Or will it just keep everything and not reset the game? Please can someone help? Dx

I activated my account but I'm not sure how to actually play the game now. I downloaded the 'FH setup and the game icon is on my computer but when I press it, it says 'programme can't start because OgreMain.dll is missing from my computer try reinstalling the programme to fix this problem' and when I click it off another one says it can't start  because 'irrKlang.dll' is missing and yet a third sign comes up saying libOIS.dll is missing. Do I need to download these? When the signs go, there is a black screen with non stop writing that keeps typing that says what looks like people's usernames and when they first logged on and off and all the dates of them. I first went on to the feral heart site and pressed login and typed my username and password then it says 'you must keep this site open while you play the game'.
This has really left me confused, because I am unsure what I need to do next to actually play the game. Can anyone explain the steps as to how I download it or what I need to do next.
