Nitrane- I don't see any information about 4.0.3, just about Poser Pro Pack, which looks like an add-in for Poser 4. Poser 4.0.3 would be, I assume, another free bug fix- the convention is that the first digit is a major upgrade (Poser 5!), which you have to buy, the first decimal is a minor upgrade (Poser 4.1) which may be free (mostly is if .1, mostly you buy if .5), and the second decimal is a bug fix (4.0.3) which would normally be free. Pro Pack looks good though, but we need more information!
