I took us ages and this topic came up at least twice in a week and we absolutely had no clue.
But now we found out why this happens.

We assume very old client versions are used for these accounts.

Years ago (yes more than 5 years) the encryption was updated and the website requires that new encryption and fails because old clients still use the outdated encryption.

Solution:

  • Download and use the latest client:
    TS6 or TS 3.6.2
  • Login into that client
Be aware that this step may require your Recovery key!
So you might get your backup or create one in Client's account settings 
before installing the latest client.
  • Try again to change email or password

If above did not help go on with following

  • Change the password in the mentioned clients (to a different password)
  • Change your email if this was the initial problem
    ** Change the password back if you like
