What do I do in the situation where John the ripper no password hashes loaded?

I am trying to learn how John works. I made a password-protected rar archive, and wrote that password inside a file named pass.txt. I used rar2john to build the hash: # more test.hash  test.rar:$rar3$*0*c15839e058bb28a3*9d55925bdd33618f3e02f8b7004faab8 However, when I try to run john, I get an error message:

# john --format=rar --wordlist=pass.txt test.rar

Warning: invalid UTF-8 seen reading test.rar

Using default input encoding: UTF-8

No password hashes loaded (see FAQ)

I tried with and without the --format and --wordlist options.

I read John The Ripper's FAQ but nothing helped me. I saw that the format rar was supported on Pentest Monkey. I even tried the example they gave, but John keeps telling me the same thing. What should I do?
