Copy the given files to a new directory and rename cuparticle v2.cls to cuparticle.cls. Then you can compile the given file fms-template.tex file without that message you got ...


The Journal is Forum of Mathematics, Pi author instructions page provides a page to download a zip file that contains cuparticle.cls. It looks like the class was developed by RVT but the download link on the wiki appears dead and the wayback machine isn't helpful.
