Small error after completed payment

This module works beautifully, at least in test-mode. I do get one error though, which seems to concern the comment section on the order-scheme:

warning: Missing argument 6 for uc_payment_enter(), called in /var/www/stripm_test2/sites/all/modules/payex/modules/uc_payex/uc_payex.module on line 247 and defined in /var/www/stripm_test2/sites/all/modules/ubercart/payment/uc_payment/uc_payment.module on line 598.

Its really a small issue, and if it is not fixed before we go into production, I will simply cut out the function - selling role access works fine without it...
