We are using osCommerce v 2.2. (We made a lot of changes, that's why we are using old version)
One day 'Priority Main International' shipping method stopped working. I tied to change the value of "intl_types" array entry, but it didn't help.
this is the Shipping Module version from usps.php file

I know that reinstalling the module could help, but I think that installing module with version 4 instead of version 1 will break some functionality.
Does anybody know how to fix this problem?
