Wont save with packed files [Blender 2.69]

when i do file>external data>pack into blend file. it says there is a jpg file missing.
i made a file of the same name and put it on a cube.
but it still wont pack the other images.
any ideas?
that IS how you pack the images to a blend file isnt it?
thanks all
i use 2.69temp.blend (555.1 KB)
here is a file with just the new cube. nothing dont to it.
still get the error message!
