My computer's the opposite for some reason... if I try to bring 3 V2 characters into Poser 4, they will start coming in with body parts missing but with Poser 5 I can bring in 8-10 V2 characters with no problems. Don't know why but I always had bugs with P4 but have only ever had 1 crash with P5 in the year and a half I've used it.
