Upgrading from 1.3.8a to 1.3.9h and thought I followed the directions right on, but when I click on "Update Database Now" it just freezes and this is what I get:


1072 Key column 'zen_order_id' doesn't exist in table
in:
[ALTER TABLE paypal ADD INDEX idx_zen_order_id_zen ( zen_order_id ) ;]


Any idea's?
