Locked out of Creator account

I signed up to creator and paid the money. I was issued with a receipt conforming I had paid. My bank account was debited.

I created my first important application and all worked well for two weeks. I was still in the process of developing it.

Recently I transferred my email hosting to ZOHO as well. I set up a few email addresses which work great.

Now I can't get in to my Creator account. Is this related to setting up email?
