Previously, I was able to send ebooks to my kindle with no problem. Then suddenly, the sends failed. I've tried disabling firewall, signing up for a gmx account, checking that the addresses were on my amazon approved sender list to no avail. I've even tried restoring the computer to the point where calibre worked and nothing has helped.

I won't post the entire error message, but this seems to be why it failed

send: AUTH <censored>
reply: '535 Authentication credentials invalid\r\n'
reply: retcode (535); Msg: Authentication credentials invalid

Sending failed...

How do I fix this? Please help!
