Something Willful

I thought I saw a Mesh Project kit somewhere. What is a kit that will work? I will but it but I need some advise and help, please

I am trying to use this product: https://marketplace.secondlife.com/p/Texture-Change-HUD-Scripts-v11/6224540 But when I click the button to add the texture, it just says "applying please wait" and doesn't change the texture. I am going to log out and back in and try it. It worked 5 min ago and then stopped, even though I didn't change anything. Please help!
