How to properly configure New Blog Templates for existing users

Hello, I’m stack with a problem cannot solve it myself. I use New Blog Template plug-in.
No issue with a new user registration. The problem occurs when user who already has an account wants to create a new site. When he clicks on the Create new Site in a member’s area he gets bounced back to the home page and there is no way to get into the site registration form. From the Buddy Press menu he can get to the site registration form but cannot see the Templates Show Case. You can log in to site with [admin login credentials removed]
Please advise. Thank you
Yuri
