Arcane Familiars

OK, I've been playing around with the classes.txt file and adding the classes from the pathfinder advanced player guide. Anyways when I make a witch and give her a toad for her arcane familiar it won't import into d20pro because " '-' does not describe a valid dice"
The toad doesn't have an attack value and actually has a negative to CMB, this causes an error on import to d20pro. I found that an easy way around this is to edit the attack dice of the .xml file and change the - from hero lab into 1d0 and it imports fine,and you maintain the 0 attack dice. Just an heads up to anyone doing the same thing. The Cavaliers Mount,and the Summoners Eidolon come over from HL just fine.
