103mm is a short BB - you certainly couldn't get a 99mm BB to create a 42mm chainline. It's probably to do with the chainring - is it mounted on the outside of the spider when it should be in the inside? Some cranksets work either way so that the outer position is for SS MTB hubs (like the Stronglight Mygal).
Or is the ring on back to front or something?
Bottom bracket screwed all the way in?
Not sure what else it could be.
