login problem when user register with virtuemart

[sahar-onyx]

Hi
I use virtuemart 2.6.0,
I set  New User Account Activation to None;
and only registered person can checkout
I use a login module in my site;
My problem is that in process of checkout when new user register with virtuemart, automically they must be login with login module
but nothing happen in login module and user must login with login module to view his situation.
