I am trying to convert a vocal PS3 SNG file to XML, and getting the following error: --- No overload for method 'Serialize' takes 2 arguments. --- It is coming from the MS CSharp RuntimeBinder. I tried it with the latest general and beta versions (2.8.4.0 and 2.8.4.1) both resulted the same error. I did used the 'vocal' option for the Arrangment type. XML conversion works fine for the non vocal SNG files. Any idea what can cause this error, and how could I fix it? ------------------ 2017-12-07 12:10:50.1371 | RocksmithToolkitGUI.Program (INFO) : RocksmithToolkitGUI.Program.Main RocksmithToolkitGUI:
