You need to create a new directory in C:\Program Files (x86)\DVBViewer\ called MDPlugins. Move all existing files from plugins directory for vPlug, NWEmu etc to there, including keys and all associated directories. In the now empty Plugins folder, copy across the files SoftCSA.dll and SoftCSA.ini - available from the post here in the RAR file, in the folder NWemu\NWemu_DVB_system_files\DVBVIWER\SoftCSA_300\Plugins. This fixed it for me
