I just tried to install Super Orders 2 on my Zen Cart 1.36 nd get the following error when running the sql through my admin/ tools:

1062 Duplicate entry 'CA' for key 2
in:
[INSERT INTO zen_so_payment_types VALUES (NULL, 1, 'CA', 'Cash');]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

What should i do now?

Thanks
