I'm using PCS to convert a fighter of mine, however I'm running into a problem that maybe you could help me with.  (I have the latest version of PCS btw).  Anyway here's my prob: when I try to convert from a cob to a pof it gives this error "Forgot to group those objects".  All I have is the ship itself (no subobjects, just the hull) and I can't figure out whats going on.  I never ran into this problem before with any of my other ships.  I know its probably something really stupid that I missed this time but can you (or anyone else here) just point it out to me.  Thanks!
