I don't know yet, why you get this problem.
In any case I would recommend to close first all other applications, before running USB_MultiBoot5.cmd
There are a lot of them running now which might interfere.
What is the path to your USB_MultiBoot5 Folder ? (use simple path without spaces is recommended)
How did you Format your USB-stick ? (what program and FileSystem was used)
I recommend also to copy your XPSOURCE from DVD to a Folder on Harddisk in a simple path without Spaces,
instead of using the DVD directly as a source from which USB_MultiBoot5.cmd has to copy and find the XPSOURCE files.
All recommendations can make the process a much easier task to fulfill.
Can you please give as Attachment your usb_prep.log renamed as usb_prep.txt file.
