Oh dear. You're right - this seems to be a bug that must've crept in with my last fix on that bit of code. I remember I had tried it all out with the CMP (community map pack) and both titles and preview were being shown and the maps could be loaded.
Then after 1.1.0.1 Gibstick and V-Man told me that loading from "show all maps" didn't work so I fixed that ... sorry, must've overlooked some aspect here - the map at least loads for me, but I'll get it fixed for the next release (which will be "soon" [do NOT ask when!]).
