Can not sign in in help center to contact you

Hi,
i tried to send you a messege through the contact form. When i hit the link to the help center, i logged out automaticly. When i try to sign in, the message “You are about to logout of Sketchfab.
Of course, you can log back in anytime.”

In the adress line i see my old email, what i changed for long time:
https://sketchfab.com/logoutkind=error&message=User+is+invalid%3A+Email%3A++w*************%40yahoo.com+has+already+been+taken

i tried this also with a browser i never logged in. It is the same error. And for sure this worked before with the newer email adress. Same on iOS devices.

Best regards, Harald

Hi Harald - could you please email Support directly at support@sketchfab.com? We’ll need to confirm your email on the account and then we can help you login. Cheers!

Hi Dan, i sent the mail.

Thanks, Harald
