AWS Customization - Setting shopping cart at login

Hi All.
I'm customizing an install of ZC to utilize AWS (amazon web services)
Everything works fine before logging in and after logging in. I can even complete an order.
With the exception that once logged in I am not loading previous cart contents though they are getting wrote to the DB.

Also, if I have items in my cart as a guest and then log in it says
"Whoops! Sorry, but you are not allowed to perform the action requested.
You are still logged in to your account and may continue shopping. Please choose a destination from a menu."

Though the items wrote to the DB correctly I am not loading them. I'm sure it's something simple I am overlooking but I burnt my brain I think.

site is "kids toys 1 dot com" (don't want to get googled yet)

Any ideas what I might have broke? Note: All category menus and products are dynamic via AWS.
So I have done a large remove and replace for these two areas. Still a lot of work to do but it's coming along.

Thanks,
Ken
