Created Unassigned: Cannot use with .Net 4 [9430]

Hi, I've been trying to use ClosedXML with .NET4, I've installed the proper installation (tried a few versions),
downloaded the DocumentFormat.OpenXml.dll file for 4 (And for 3.5), and also tried using the SDK dll (SDK 2.5) that's in my Program Files dir, and nothing helps.
It compiles ok, but in runtime I get:

{System.IO.FileLoadException: Could not load file or assembly 'ClosedXML, Version=0.76.0.0, Culture=neutral, PublicKeyToken=fd1eb21b62ae805b' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

}


I tried all the options with the properties of both DLLs - "Copy local" (true of false), "Specific Version" (true or false and what not.
Nothing helps.
I've even tried using .NET3.5 ClosedXML with OpenXml v2, and even mix the openXML and closedXML versions (.NET4 with SDK2, .NET3.5 with SDK 2.5, etc')
Any ideas?
Thanks
