Need help solving problem-checkout process

I have OpenCart 1.5.1.3 on 2 different stores & both stores have essentially same issue.

My stores are: http://www.411healthstore.com & http://www.marinephytoplankton.com/shop/

The problem is with the checkout process-step 2 (account/billing) it gets stuck in loop & when it does clear says email address is already registered-even if I use a madeup new address. Othertimes it gets stuck with Authorize.net in an endless loop-eventually we can see Authorize.net has taken it, but we never reached a success page on our cart.

I need someone who can fix this for us or guide me as to what to do.

Hi,

Opencart depends on the Jquery library
Grab a copy (same version as the one you are using) of opencart and look for these folders

/store/catalog/view/javascript/jquery/ui/
/store/catalog/view/javascript/jquery/ui/themes/ui-lightness/

These 2 files are in those folders create the files on your server and upload the files to the server your server

jquery-ui-1.8.9.custom.min.js
jquery-ui-1.8.9.custom.css

If the problem is solved pretty sure it is add [SOLVED] to the title of this post
Kind regards Werner

Thanks!
