How can I use Magick in Unity?

I have downloaded the suggested version of http://magick.codeplex.com/releases/view/614781. I dropped it in my Assets folder. I included it in my C# scripts, and all of the code compiled without any issues. (It found Magick, and accessed the library fine.)

However, when I switch back to Unity, I get a couple of errors. One error is very non-descriptive, but with a bunch of information and different suggestions on the Unity forums. After trying all of the suggestions, such as setting the API compatibility level to .NET 2.0 and reimporting all assets, I still have the errors. The first one is there all of the time, and the second one is there only after I reload my project.

The other error is fairly clear, but I just don't know of any repercussions of fixing it incorrectly. I figured I would come back to it, and only included it here in the off chance it was related to the first error.

Is there any way I can get my Unity code to compile with the inclusion of Magick?

Second Error

 Multiple plugins with the same name 'magick.net.wrapper-x64' (found at 'Assets/Magick/net20/Magick.NET.Wrapper-x64.dll' and 'Assets/Magick/net40-client/Magick.NET.Wrapper-x64.dll'). That means one or more plugins are set to be compatible with Editor. Only one plugin at the time can be used by Editor.
