This looks a bug that was fixed with a more recent version of Crowbar.

Two possible solutions: Use definebones or use latest version of Crowbar.

*sigh*

You grabbed the source code, not the tool.

That is very cool. Thanks for posting.

:)

Portable binary:

  Removed until major bug is fixed that could delete entire folders when using the Unpack features.

I do not know anything about the DMX format or the blockname option.

You have probably forgotten to replace something or moved something like a $sequence or $animation out of order that the compiler needs.

Because the compile log shows " SMD MODEL ../animations/dmx/SECONDARY_aimmatrix_idle.smd" before the error message, I would expect the problem to be inside the macro at line 140 of the "demo_animations.qc" file:
$MPWeaponAims_lefthandIK SECONDARY $infoNode$

Line 6 defines the $infonode$ variable with the name found in the error message:
$definevariable infoNode "demoInfo"

So maybe you need an $animation or a $sequence with the name of demoInfo before line 140 to avoid the error.

There is the possibility that the underscore in "Exurok_Door.smd" is the problem. Try using this for the model line (be sure to actually rename your smd file as well):
$Model "Door" "ExurokDoor.smd"
