can not access Mein O2 using O2 Home L tarif

Hello,
I'm a newbie in the city. 
I've ordered a sim with O2 Home L tarif for my home, I've got it, and I am successfully using it.
Also, I've already received all welcome messages, but I still cannot log in to mein O2.
The system cannot recognize my existing email, but emails are delivering to this email.
I created this account in an attempt to find any help.
I want to link in this email my O2 Home L account for possibilities to manage my data, sim, etc.
Could anybody help me with it?
