Please uninstall the software using MlDmxCleaner program (download available
here). You should unzip, install the program and start the MlDmxCleaner.bat.
To get the new (fixed) Demultiplexer version you should download the
Elecard MPEG-2 Decoder&Streaming Pack.
There is no need to purchase and activate this pack if you need only fixed Demultiplexer version! The Demultiplexer filter hasn't any activation mechanism! But if you are going to use the Elecard MPEG-2 Video Decoder I recommend you to purchase and activate the package.
