Texture Problems with Red/Dark/Gem Armor

[Rarity]

Hello! My boyfriend and I have been using Tekkit for quite some time. We love it a lot and have had no bugs that we can find.. until we finally made our first piece of Red Matter armor. My excitement faded when I was met with this:

Now, before people suggest the obvious:

• I tried on single player and on multiplayer.
  
• I tried with the default texture pack.
  
• I tried replacing the armor texture with an existing armor texture in my texture pack.
  
• We are using the latest version of Tekkit.
  
• The only other mod we have installed is MCMMO.
  

The top of the character's head has "G1" on it. I can't figure out what is wrong, and this effects all players.

Thank you!

I'd like to add that the texture bug appears with Dark Matter, Red Matter, and Gem Armor respectfully. All of the armor produce the same white texture bug; Vanilla armor is unaffected.

Seems to work fine for me:

I suggest changing your texture-pack and see what happens...

EDIT: Whoops, didn't read you already did that.

In that case, try reinstalling Tekkit. (Backup your save first ofcourse)
