mastercard not working with securepay

[Briohny12]

I have Zencart Version 1.3.7

I installed the Securepay module 2.1.1

Everything works fine except for Mastercard. It returns the error message "The Credit Card Number does not match the Credit Card Type."

The CC details are correct.

Securepay are telling me that they are seeing the transaction however the information is being passed in an incorrect format.

I have tried uninstalling, deleting files both locally and on the server and then re-uploading and then re-installing - still the same error.

Any advice would be very much appreciated.

Thank you in advance.
