Try starting winpm-32 using command line including -o to start in offline mode. See Help, Commandline options. It may not be possible to Edit and save file while open and locked as would be the case if the .pnd file is in use and connection is active and the indicator is showing red as when connection is hung. You can get to it using other Identity while winpm-32 is running because the affected connection and .pnd are not open and locked at the time of edit and save.
