Texture not showing up!

I am using a cracked texture for my screen. Frames 1-25 are transparent, so you can’t see the texture. but frame 26-107 should have the crack texture, but it isn’t showing up. What am I doing wrong?
ps. This is a separate object.

Use File / External Data menu to pack all textures into your blend file before saving. Then upload to http://www.pasteall.org/blend/ and tell us the download link.

Also please use the appropriate forum.
