Help compiling a silverlight project!

Hi every body I try to compile my project' but I get this error:

Error 1 The "ValidateXaml" task failed unexpectedly. System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Documents and Settings\arielih\My Documents\Downloads\פרויקט\RubikCube\obj\Debug\RubikCube.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) File name: 'file:///C:\Documents and Settings\arielih\My Documents\Downloads\פרויקט\RubikCube\obj\Debug\RubikCube.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. Thi开发者_如何学编程s release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

RubikCube

What should I do?

If you downloaded the file RubikCube from the internet, it may be blocked. Right click on it in the explorer and "unblock it" in the file properties.
