If you are encountering one of the error messages listed below when trying to link your Klei Accounts:
“Please Verify/Validate the email address in both Klei Accounts and start the process again”,
And/Or
"Please update your *Klei Accounts* to use the same e-mail address and start the process again",
This means that the Klei accounts you are trying to link are either not using the same email address, or the Klei accounts have not yet verified the email address on the Klei Account, or both.
To fix these errors, you will need to log in to both Klei accounts separately, and ensure both accounts are using the same email address (found in the USER INFO tab), and that email addresses for both accounts have been verified. The account linking process cannot continue if one or both account emails have not been verified.
Once both the Klei Accounts are using the same email address, and the email addresses have been verified for both accounts, you should be able to complete the account linking process.
