I don't have the file sets to hand at the moment but it should be easy enough to locate the suspect file.
Using the Item ID number that the error throws up you can open the menu_ini in Notepad, hit Ctrl+F and enter the ID number. This will take you to the block which contains that information. From this block you can find the TGA file which is missing or altered.
Do this to the Integrated Orders & Default menu_ini files to compare differences.
If the IO mod was corrupted, you would receive numerous errors about missing ID's. I know, I've been there.
