Ive had problems like that with w models.
What i did was delete that line of code in the QC and it worked, it might be different though for you.
I would suggest a backup before you modify.
I hate that compiler anyways
I use GUIStudioMDL
Try deleting this like of text:
$hbox 6 "ValveBiped.Bip01_L_Toe0" -2.860 -2.810 -2.860 4.000 1.200 1.720
Thanks guys, i deleted that line and it compiled fine.
