I still have P5 installed with P6 because of P6's problems initially. I have made a file in P6 and opened it in P5 but it always gives an error message but then opens it anyway. My own view is that you will only get a problem if you have the new P6 compression thingy's switched on, mine are off by default in my preferences to avoid those issues. thefixer, poser coord.

Injustice will be avenged.
