Johnny.
In your first post you state that the cr2 gives an error message.

Down here you say you imported the obj file in Poser, build in Max and ungrouped,  .
Where does the cr2 come from?

---

Poser has a setup room to build conforming clothing.
The setup room can rig, and autogroup an imported ungrouped obj file.
And the output is a fresh grouped obj fle and a cr2. => the conformling clothing.

---

It is in short and in large in the manual, and at least a dozen times on youtube.
There are also video tutorials by CP/SM  on their own tutorials pages.

---

From what you write here?
Building an ungrouped object, importing that object in Poser and getting a cr2 error makes no sense at all.

I fear you are mixing things up.

I fear you have been trying to follow something written before Poser setup room had a working autogroup function.
But now I am guessing completely in the blind as the information you give is confusing.
