I've been messing with this the better part of a week and this is what I've found. First of all, I'm using:

1. Windows 10 Pro with the latest patches
2. Poser Pro 11 SR 5
3. DSON 1.1.3.50
4. D3D's Library Manager XL latest version
5. DAZ Studio 4.9

It seems that Library Manager XL is failing to properly do the conversion to triax. It should do that automagically and it does in Lululee's nice video tutorial but it doesn't for me. So here's a work flow that gets G3 and all expressions into Poser for me:

1. Load desired figure in DAZ Studio.
2. Convert figure to triax and save
3. Use Library Manager XL to import the figure you converted to triax into Poser
4. Save figure in Poser
5. Find resulting cr2 file and load into Willdial's G3 Poser updater, convert and save
6. Go out and have celebratory drinks ;P

I hope this helps someone with the same problems I was having. I think my issues have to do with the latest version of Poser Pro 11 as an interesting thing is happening when I try Lululee's work flow: the resulting figure is loaded as skinning method "simple bones single skin - interoperable" rather than as "Poser traditional" as you would expect. Strangely, the expressions work in that case but all the rest of the joints are messed as in Willdial's first post here. >.< The work around pre-converted triax file loads the way I would expect with "Poser traditional" skin.

As you say, dear Willdial: "Ah, the joys of transferring between systems!"

I finish this long and boring post with a "THANK YOU!!" to Willdial and Lululee! <3
