Error Message w/ HUD

Hello,

So I’m having some issues trying to update my mod with the latest ADK patch; 255.5. Since it’s a HUD-based mod, I want to get the “PlayerHudNew” into my mods folder, but I cannot rename / edit / save it without getting this error message:

Does anyone know what I am supposed to do?

If I had to make an uneducated guess, that’s the animation you see when you open up the widget and select the canvas (on the left). At the bottom you’ll see the animation sequence.
