thats what this is. The amount of shit you have to go thru just to get a error telling you that it cant find a .dll file and the dll file in queston is non-existent that just shows you how much effort went into this shitty attempt at a mod
I'm sorry that you're facing difficulties. Typically, this is when there is an older version of the SDK installed for another mod, make sure you are on the pre-release branch of the SDK.
