Ultranova would it make any difference if I said I had got it working for 0.14.0preview2 but used the mod upgrader to upgrade it for 0.14.0preview4?
Ah yeah, the mod upgrader only works with 0.13.9 mods, it won't work on mods that were already upgraded to a preview build sorry.
I think that only major change in preview4 was the part/door/ship/mod IDs are required to be in author.id
format, which is easy enough to do by hand.
