I just tested and discovered it is the flexcontroller name that can not have the period in it.

To fix, for example, change these lines:
to (remove period):
OR to (wrap in double-quotes):

Multiple $model is valid; previous post is incorrect.

Line 112 (as noted in the error message is this:

Most likely the flex name (the VRC.AA after the %) does not allow a period ".". Remove the periods from all flex names.

For example, to change the VRC.AA flex name, you would need to change these lines:
to something like:

NOTE: Do not use underscore "_" to replace the period because it has a special meaning.

Thanks for the bug reports. Not sure why the problem appears sometimes, but I should be able to at least keep Crowbar from crashing.

Make sure you are using the latest as of this post, Crowbar 0.71.

yes

I have tried many times to "un-delta" the anims, but have always failed.

Modders work around this decompile problem by re-creating those delta anims.

Reset the Crowbar Settings file:
Go to "%appdata%\ZeqMacaw\Crowbar 0.71". Delete "Crowbar Settings.xml" file.

Most likely the GMA unpacking failed in some way. Try using Crowbar's Unpack to unpack the GMA.
