Do you have the iTunes media or the iTunes library on the external?
The iTunes library is the iTunes folder. In this folder is the iTunes library.itl file, iTunes library.xml file, Album Artwork folder, iTunes media folder, Previous iTunes libraries folder and maybe a few other files.
I purchased a new computer, installed iTunes and changed the location for my library in the advanced settings
That changes the location of the iTunes media, not the iTunes library.
To select a different library, hold Option, launch iTunes and select Choose library then select the iTunes folder.
