To set up a new account, you need to start a 14 day free trial here.
If you have a previous account you would like to reactivate, then you must login with the email address you used to sign up with. From there, you can pick a plan and continue where you left off.
Let me know if this helps!
Can you share a screenshot here? That would be very helpful!
I would also recommend ensuring you are using a supported browser that is fully up to date.
Looking forward to hearing back from you soon!
