My site was working fine for the last year until I made the switch to Express Checkout from Unicode Systems. I paid the $ and the extension didn't work, only brought the site to a round of errors. I unistalled the extension and everything seemed to be fine until I noticed that you cannot place an order when logged in as a registered user. There is no problem with guests checking out only those who are logged in. Please, any help is much appreciated.
Here is the site:

Thank you in advance for any insight or help.
