manage payments page doesn't work

Hi, Tomorrow is due my renewal, and, in the email you sent me to remind me, said to check my bank details.
I tried twice accessing the "Manage Payments" page. It asks your email, and then says that an email was sent.
I didn't receive the email. I looked in spam and other categories.
If you can check please, would be great.
I don't want to miss paying, because the courses are absolutelly brilliant.

Thank you.
