I've been trying to contact you by email but have not yet received a response. I bought the integrated version of the x-cart one page checkout module. I am using x-cart 4.1.9. The SQL patch provided fails to install automatically or manually. There isn't a mention of it in the installation instructions. In any case, when clicking the module link in the admin section, I receive this error: INVALID SQL: 1054 : Unknown column 'validation' in 'field list'
SQL QUERY FAILURE:SELECT name, type, validation, comment,value,variants FROM xcart_config WHERE category='MM_Checkout'
And I cannot configure the module's options.

Furthermore, when the module is enabled, many customers aren't being charged shipping for their orders.

Please help.
Thanks.
