You will need to change your file associations to remove the --started-from-file parameter for both the "Play with" and "Open".
The easiest way to do this is using the registry editor - regedt32.
Foreach of the HKEY_CLASSES_ROOT\JakstaMP.* folders look in shell\Open\Command and sheel\PlayWithJakstaMP\command folders and edit the Default key to remove "--started-from-file"
