A great tool, but apparently they just don't care about their existing users. I'm sympathetic about having to make the name change, however the transition should not have affected existing accounts. Instead, the password reset does not work at all and I have no way to get into my account (if it even still exists).
It was a fantastic tool while I had access, and yes I didn't use it for some time due to projects that I was working on, but now that I need it, nowhere to be found. I have tried reaching out here, emailing, and nothing. Such a shame.
