What does the complete log say? It should be very long, as you're calling
filebot hundreds of times per week.
The complete log will contain at least 190 lines of
Activate License logging:

Typical users will see this message once a month. You can confirm if your setup is working correctly by yourself by counting how often
Activate License appears in your logs per month.

If you can't find 190 lines of
Activate License logging, then you're using
filebot without --log-file somehow somewhere.

This just means that
--output did not exist when the
amc script was called that one time, and so the script aborted immediately. This is completely unrelated to licensing.
Code: Select all
Illegal usage: output folder must exist and must be a directory: M:\plexmedia

All persistent data related to caching and licensing is in the
%APP_DATA% folder, which should be on your local hard drive and thus not be affected by failures in your network drives.

The next step are as follows, I will unban your license, but if you don't fix the under lying issue, it'll just get banned again after a few weeks. I can assure you that this is a unique issue specific to your machine, no other licensee is affected. It could be anything, it's your machine after all.

You will also need to get into a habit of checking your
Junk Email folder and figure out how to configure your email service to make it deliver important emails into your
Inbox:

EDIT:

Though one similar case that I can recount was, after wasting lots of time, the user remembered he had some strange program installed that would regularly delete
%APP_DATA% files. There was no possible way for anyone to have guessed that.
