--show is always used to show the cracks for a specific oclHashcat session after the actual cracking process is done.
So it would look like this:
oclHashcat64.exe -m 2811 --username hashes.txt dict.txt
after that actual cracking process is finished, you display the cracks with --show:
oclHashcat64.exe -m 2811 --show --username hashes.txt
hmm I'm wondering why you are still not banned, since you did not follow the forum rules: https://hashcat.net/forum/announcement-2.html (which you did accept). Don't post hashes!
