Are you using PayPal? It sounds like you’re trying to force using what the person enters in your forms and PayPal is expecting them to use what is at PayPal. When they don’t match you get that error. You can change it in your payment gateway settings.
As for altering the form fields you might need to start over with them.
You might be able to do it using this plugin https://wordpress.org/plugins/wp-e-commerce-store-toolkit/
If not you can do it manually my renaming the checkout form table using something like PHPMYADMIN
After renaming it disable and enable the WPeC plugin to have it rebuild the checkout form table.

Thank you for responding to my inquiry. As to your question I am using Paypal. However, not sure what changes I need to make. Paypal worked before upgrade. Would appreciate some clarification.
Regarding the check out form. My form is now set at “default form.” To rename the checkout form table, are you saying I should create a new form by giving it the name “phpmyadmin”, but not actually creating the form. Just enter the name above and save it.
Thank you for any help you can give me in this regard.
PHPMYADMIN is a tool used to manage your database.
there is a table named “wp_wpsc_checkout_forms” I rename it to “wp_wpsc_checkout_forms-off”.
then turn the plugin off and on again when you enable it it will rebuild this table as it was default.
as for the paypal settings make sure the following are set this way
Send shipping details = NO
Address Override = NO
