just make sure that the input is correct and also remember that the way to do it is 2-fold (2 steps are needed ), i.e. first crack such that the cracked hashes with password end up in the .potfile, only after you cracked the hashes the second command can be used with --show to show the cracks.
the input must be correct. that means that all hash list must contain all lines in this format: username:hash
The file original_MD5_hashes.txt must also be formatted like this: username:hash for each and every line, this is the so-called original hash list (with usernames). That is why you always need to use --username
Maybe just try a simple example with one hash first, to see if you get it working.
It's definitely working for me (and for many other users that also did use this command !).
