I have downloaded Arc 3.1 and Racket in my Windows 7 machine, and solved many errors while proceeding. But still when I run mzscheme -f as.scm it never returns to the prompt (as if there was an infinite loop). When I use mzscheme -m -f as.scm, it shows
main: not defined or required into the top-level environment
and localhost:8080 comes out blank.
