UE4-core.dll error

I’ve looked online for about 3 hours over the past week (been busy with other things) but now that I have spare time I want to get this error finished, anyone got any ideas. I did have it working a while back but now it won’t let me launch just gives the UE4-core.dll error so I cannot use the devkit.

Hi mate
Every time the steam client update ARK dev kit you have to download a new patch from:
