I can't sign in to ePrintCenter though I could before.
The error icon "X" and the error message "Invalid email" were shown above the form "Email" after I had tried to sign in.
So I tried to "Create an account" and the error message "Please sign in at ePrintCenter.com or create an HP Connected account using a different email address." was shown; I failed even to create a new account.
My e-mail address is likely invalid but they say that it exists in the system.
I guess this happens after Snapfish service ended in Japan. ePrintCenter and Snapfish service were connected, weren't they?
They said to have deleted my account data of Snapfish with e-mail announce. I think it causes this broblem.
How can I manage this problem?
