Just had a look at your cm2 and did  a test of saving cm2 from Poser 7 and PoserPro 2010...

It is one line in every channel that's causing all this trouble...

rotateY yaw
*   {*
*   keys*
*    {*
*    k  0  -76*
*    }*
*   staticValue 323*
*   }*

As you can see, staticValue (323) is different from the k statement (0 -76).
This line gets created when saving the cm2 from Poser 7, and Poser 7 reads this line,
when loading the cm2.
PoserPro reads the k statement and ignores the staticValue.

When saving a cm2 from within PoserPro2010 no staticValue line is written to the cm2 and the cm2 loads fine in Poser 7 and Pro2010...

Usually, staticValue is identical with the second value of the k statement...
at least for pose files...

The why and how is a question for SmithMicro, or someone who knows more about Poser's inner workings than me :-)

 

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.
