Feral Heart

Hello! As I was logging on to FH, I noticed this:

A black head.
No matter how much I moved those colour sliders, the blackness remained.
As I delved deeper, I saw this:

ALL the current canines on my computer had black heads.
I did NOT modify the files in any way, NOR editing a file as a preset/texture.
I have Tearless textures, and an item pack which I cannot remember the name of. I am also on a Mac, running FH on Wineskin Winery, which is working absolutely perfect.
I know that when you have a marking pack you don't have, others see you as a "marshmallow".
I am not using a marking pack.
Tearless was working fine yesterday until today...I cannot understand why it's like this.
All the files of canine is:
cbodyMask numbers 1 and 2, cbodyShade.jpg, ceyeMask1_0.png, cheadMask numbers 1_0 to 5, cheadShade.png, ctailShade.png and ctailMask.png.
Is there any files missing? I would like an explanation for this...

Okay....but yesterday Tearless was working fine. But now, it's all weird O.o
I did not modify the files, nor opened a file to edit it. It just suddenly happened.
So all the -other- cheadMasks get deleted?

Also, I would like to ask for help on this topic, please...I would not like to post an entirely new topic. As my question is quite similar.
When I logged onto FH to play for a bit, I noticed this:

A black head. I tried to adjust the colour, but it remained black.
Any explanation for this? I am using Tearless wolf textures, and I am on a mac. I looked through the files and saw that none of the chead.png/cheadShade.png/cheadMask.png, etc. were missing (At least that's what I think)...And I am using no marking pack.
Any explanation/help for this?

Also FH kept crashing.
