"Greetings,
The error you're describing indicates that you've attempted to claim an invalid
authentication key. In some cases the authentication key may be difficult to
read and it's also very easy to enter wrong letters or numbers when typing it
in. Here are some common substitutions:
- B's and 8's look alike.
- 2's and Z's looks alike, Z's and 7's look alike, and sometimes a 2 looks
like a 7.
- 4's, A's and H's occasionally look similar, especially if the left side of
the H or A is faint.
- G's look similar to 6's.
- E's appear similar to F's if the bottom of the E is faint.
- K’s can look like R’s due to their proximity to the text above the
authentication key.
Please carefully examine the key to ensure the correct letters or numbers are
input.
