Mudbox Help needed

[Aki K]

If there's anyone on here who uses Autodesk Mudbox, I could use some expertise. I tried going to their forum, but their website is broken and it keeps reloading the page and I can't access the forum or post.

 

My problem is simple. I had a .png image I was using as a stencil. Let's just call it "Aki.png."  I deleted Aki.png a full year ago. But I keep getting an error message everytime I boot up Mudbox, select the paint brush tool, or select the stencil tool saying "Mudbox cannot find folder/subfolder/Aki.png."   And if i create an Aki.png just to get rid of the error, the error message becomes: "Mudbox cannot find folder/subfolder/Aki - copy.png"

 

I just want the error message to go away. I don't need to recover the stencils or anything. I deleted them on purpose, the project was done. Just need to stop Mudbox from trying to find files that have long ceased to exist.
