Problems With the usra_imbount_b0

Hi guys i was having a problem lately with the usra_imbount_b0 it has only 4 errors. Im not sure how to fix them or some sort
so here are the errors:



Unable to load primary texture 'windows.tga' for texture file 'windows-windows_a.texture.txt'.
Unable to load alpha texture 'windows_a.bmp' for texture file 'windows-windows_a.texture.txt'.
The primary and alpha texture are not the same size for 'windows-windows_a.texture.txt'
Binary conversion failed for texture resource 'windows-windows_a.texture.txt'.
these are not my first errors before i got them on other engines or something

If you know how to fix them leave a comment
