e-mail issues

Hi,

I'm running the abovesaid version of EC on a Drupal 5.1.

I've been trying to configure e-mails (E-Commerce > Mail) and my List of Mails shows 9 types of mails.
5 of them seem to work ok, but for the other 4, I get these messages:

Default email confirmation: Fatal error: Call to undefined function: token_values() in /home/libracom/public_html/sites/all/modules/ecommerce/contrib/ec_useracc/ec_useracc.module on line 593

Default expiration notice: warning: Invalid argument supplied for foreach() in /home/libracom/public_html/sites/all/modules/ecommerce/contrib/ec_useracc/ec_useracc.module on line 282.
user warning: Table 'libracom_drupal.ec_shipping_transaction' doesn't exist query: SELECT service, method, cost FROM ec_shipping_transaction WHERE txnid = 0 in /home/libracom/public_html/includes/database.mysql.inc on line 172.

Default renewal reminder: warning: Invalid argument supplied for foreach() in /home/libracom/public_html/sites/all/modules/ecommerce/contrib/ec_useracc/ec_useracc.module on line 282.
user warning: Table 'libracom_drupal.ec_shipping_transaction' doesn't exist query: SELECT service, method, cost FROM ec_shipping_transaction WHERE txnid = 0 in /home/libracom/public_html/includes/database.mysql.inc on line 172.

Default welcome mail: Fatal error: Call to undefined function: token_values() in /home/libracom/public_html/sites/all/modules/ecommerce/contrib/ec_useracc/ec_useracc.module on line 593

Any help would be greatly appreciated ...
