Hi getourtunes,
I replied to your private message, but will post a similar response here in case others hit error 6.
Error 6 is an SSL error, which indicates that the network connection to
jammr.net is untrusted.
Have you installed any “certificates” on your computer recently? Sometimes they are required by internet providers or virus scanners but they can interfere with SSL connections.
Did logging in work for you before? SSL issues can happen on specific networks like hotel wifi connections.
