Hey Macey, the 32-bit version of PP2012 should work OK for you. If it doesn't, start a thread in the main Poser forum and detail your problems and we'll help you out.

Dawn will work just fine in 2012, so you'll be able to play.

All you need to know about weightmapping is:

a) figures bend better;

b) weightmapped figures won't work in older versions.

Easy!
