Ok ..A quick update !
The problem of the upload button disappearing seems to be caused by an incorrect scale setting during LOAD inside of the "maxslav" plugin by default it is set to 40 ...upon changing this to 1 I can now upload using v3 !!! and the size issues in my previous post are fixed also !!! There are still a few little discrepancies with the rigged mesh (like a little piece were its not supposed to etc) but its another step forward....
*I should mention tho even with the scale problem (set to 40 ) I could still upload the rig with Kristens latest build* << just FYI
Now to learn how to makes some mesh clothing
