Не удалось загрузить сборку. Сведения об ошибке: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Program Files\Autodesk\ModPlus\ModPlus_2014.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///C:\Program Files\Autodesk\ModPlus\ModPlus_2014.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. This 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

И не нужно будет покупать все подряд - только то, что нужно вам. Пока что все в разработке (там идей больше чем свободного моего времени)
Это неописуемо, спасибо автору, правда скачать выйдет немногим позже
