It worked just fine in the 3.5 stable version, but after upgrading to the lastest development branch (3.6), it no longer works, giving me this error on effect = content.Load<Effect>("fileName")
An unhandled exception of type 'SharpDX.SharpDXException' occurred in SharpDX.dll
Additional information: HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.
Any help is immensely appreciated.
