report.tex, report.bib, buIE47x.cls files and (figures subfolder if you have one) must be directly accessible — do not place them in a subfolder inside zip. Move the files from inside ARIMS-17 folder up, so they are visible when zip file is opened. Check the pictures on the submission web site.
See below the picture of zip content after files inside ARIMS-17 are moved up and the folder is deleted.
A common mistake is to zip the folder containing the files on your computer. Instead, enter inside the folder, select all files and subfolder, and then zip everything.
