Missing Texture files

I have an old file in X2 which I have not opened in awhile and am using on a new computer...

Obviously I have failed to load my previous configuration back completely, for it appears that certain textures are missing...

I am getting several of these messages when viewing in 3D:

D:\P4\dev\Releases\12\chief\source\TextureManager. cpp(138): Warning #272029401
"A surface is using a texture that can't be found: C:\ProgramData\Chief Architect
X2\Referenced Files\CulturedStone.zip#zip:csv20008t.jpg"

Build: 12.6.0.25

How can I identify which items these are applied to and apply different textures?

Thanks.
