The email you got actually said what the error was, but it was way down at the bottom where folks often miss it. There was nothing wrong with the md5 or the files themselves, but you omitted a .txt file that is a required part of every upload to the Live Music Archive. The system can occasionally create one based on the information you provide, but we recommend rolling your own because the format is quite often janky.
In this case, it looks like one of the other admins created a txt file for you and uploaded it, so the show is fine now.
A link to the logs can be found by clicking "Edit item", then going to "Item manager" - look for the button labeled "show history for item". That should take you to this screen:
