Missing Textures/Graphical Glitches(Pink/Blue). Please help!

The latest update gave me a lot of headaches. It had a ton of errors, and my launcher was forced to repair. Six hours later the game started working. But now I've encountered a new issue. Some armors are now missing textures.

Some armor pieces are shown as pink in-game, and blue in the preview window with some weird letters. I browsed about this issue and they all mention the same thing: run the Repair. Which doesn't work? It's grayed out. I CANNOT select it. I don't have the ST letters nor anything related to BitRaider. All of that is gone, but now I can't even Repair the game's launcher again. I would really, really hate re-install.. especially since the BitRaider issue would become an issue again. 

Is there a way for me to activate the Repair? Is there anything that I can do? This issue is EXTREMELY annoying, and I thought that it was happening to everyone else since other sets were suffering different issues, but apparently it's just me.
