Installed latest payflow Module in Zen 1.3.7.

Installed no probs
I also have the latest express and patch installed and IPN also (intend just running payflow and IPN without the agro of express as too many options seem to confuse most people!), but have "switched off" the Express module for the moment.

Created SSL cert from paypal and placed in folder and placed file path in payflow module.

Did a test purchase with my own Visa card, and worked straight away.
Did a test purchase with my own Switch debitcard and it keeps coming up with the warning bar saying the expiration date is invalid?

Noticed that none of the test card numbers in the module include switch cards.

All card types are switched on in Admin.
No zoning restrictions on any payment methods.

Checked my includes/classes/cc_validation.php to see what cards are supported, and Switch/maestro e.t.c are all there.

Has anyone else found this problem?

Thanks for the module, and in advance for any help.
