I can log in with Google, but this account does not have the Tourer subscription.
So I need to login with my other account, but it does not allow me to continue.
Because I have no Facebook Account any longer, also this way is no option for me to log in.
Why is it not possible to log in with my email address?
Obviously my email address is well known by Kurviger, but the message that I get displayed seems to belong to a registration process, rather than a log in.
I replied to the email you send earlier as this also contains your actual email address.
The problem is security. We use default security procedures to allow access to your account. You can only log in with the means you authorized Kurviger.
If you want to add an email login to your account, you need to sign in first with your existing login option, then you can add an email login. If you deleted your Facebook account that is not possible anymore.
