The party line. At least the one that Wired Lamp gave was that game entity limit was too small in MP to be able to load the SP maps.
This problem has been corrected in JKA and I'm currently working on a CoOp gametype for OJP. In theory this will allow you to play the JKO maps in CoOp mode as well. However, you will have to have JKA to play.
