I have a consistent CTD as well whenever I attempt to select a third party livery for the A330-300 RR (Fanhansa for instance). The instant I click on the livery, the sim hangs and then CTD without an error message.
EDIT: I was able to finally select a livery by first choosing a different model (CTD happened on 330-300 RR, chose 330-300 GE), then swapping liveries and then switching back to the 300 RR and I was then able to choose the livery I wanted without CTD. However the sim hung on pressing Fly Now (started the zoom out animation) and then CTD, again with no error.
EDIT #2: Unable to use the A330-300 at all, CTD on Fly Now no matter what livery chosen.
