Smarty problem

I am using smartys in other areas of my site without problems but am having trouble pre filling an opt in form using these:
{$smarty.session._amember_user.login} and
{$smarty.session._amember_user.email}

I do have amember set to automatically log in customer after signup so the way I see it they should be working.

They were working when I first set this up a few weeks ago. I had a problem with my domain and the registar locked it out. The problem with the domain has been resolved and I now have control again.

I have not installed the newest version of aMember and am running 3.1.8.

Any one have any ideas why these smartys wont work now?

Thanks,
Jim B
