catalog/checkout_process.php

@line 73
find:

if ( ( is_array($payment_modules->modules) && (sizeof($payment_modules->modules) > 1) && !is_object($$payment) ) || (is_object($$payment) && ($$payment->enabled == false)) ) {
tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYME NT, 'error_message=' . urlencode(ERROR_NO_PAYMENT_MODULE_SELECTED), 'SSL'));
}

replace with:

if ( ( is_array($payment_modules->modules) && (sizeof($payment_modules->modules) > 1) && !is_object($$payment) && (!$credit_covers) ) || (is_object($$payment) && ($$payment->enabled == false)) ) {
tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYME NT, 'error_message=' . urlencode(ERROR_NO_PAYMENT_MODULE_SELECTED), 'SSL'));
}

2 days of work to undestand it!
Enjoy!
