The presets file is empty. You can load a XML presets file such as the one that comes with the TapinRadio application. However, I cannot find such a presets file with that application (only presets.trd, which is not in a XML format). If you want to load a presets file MB asks for a presets.xml.gz file. Does anyone know what its format or layout is? I could build one myself if I knew.
