Can't Sign in to Graphicall

“Authentication Error. Not a valid Open ID”

Hi, I’ve been a member at http://www.graphicall.org for some time but now for some odd reason the website won’t let me sign in. I get the message above when trying to sign in. They’ve sent me a temporary password but I still can’t sign in. Does anyone know how they can be contacted? Thanks.

Same with me :confused:
