Go back to the original HUD folder, right click, go to properties, make sure Read Only isn't checked off. Start the launcher. It should overwrite the modified files to their original form. Start the game and see if it's fixed.
You only have to make a copy of your HUD folder if you don't want to lose any custom files. If you don't care and the problem is fixed, you can just delete the copied folder.
Please let me know if the problem is fixed.
