====== Doors and plug-ins ======

===== A plug-in will not load =====

  * **It is the wrong kind.** A Win32 ''ProBoard.exe'' loads only Win32 plug-ins, and an x64 one only x64. Windows reports error 193 ("not a valid Win32 application") when they are mixed. Keep one kind in the ''PEX'' folder.
  * **It is an old PEX file.** ''.PEX'' programs from 16-bit ProBoard do not run. Use the ''.P3X'' version.
  * **The interface version changed.** A plug-in built against an older interface refuses to run until it is rebuilt. See [[v4:sdk:overview|Plug-ins and the SDK]].
  * **The menu data is wrong.** It must start with ''/I'' and then the plug-in's name. See [[v4:reference:plugins|Plug-ins]].

===== A door-network game does not connect =====

BBSLink, DoorParty and Skull Crash each need their own settings file with your credentials, and a connection out to the network. See [[v4:doors:door_networks|Door networks]] and [[v4:reference:ports|Ports]].

===== A native Windows door does not start =====

Check the door's line in ''DOORS.PRO'', the path to the drop file and the node's ''NODEDIR\NODE<n>'' folder. A door whose drop-file path changed between releases may need its command line edited. See [[v4:doors:native|Native Windows doors]].

===== A DOS door does not start =====

DOS doors run through PBLegacy and DOSBox-X. See [[v4:doors:legacy_dos|DOS doors with PBLegacy]].
