Sell Prices Not Saving

I am using Drupal 5.5 with PostgreSQL. I recently upgraded to the Bazaar verison a few days ago to resolve another issue. As a result, I am now have a more critical problem that prevents checkout from occurring for all products.

With one of my cart link URLs that was previously working (/cart/add/p230_q1_m0?destination=cart/checkout), I received the following error and the link only took me as far as the cart screen (not the checkout screen).

The minimum order subtotal for checkout is $1.00.
Upon further investigation I found that my product prices had been wiped out with the upgrade to the Bazaar version (I only had 2 products set up so this might be a bigger problem for others than it is for me). I then edited one of my products to add the sell price and saved. I tried the cart link again and got the same result. It appears that sell prices are not saving and therefore everything is $0.
