Rewards point module broke last night. I tried reinstalling it. now I get the follow error log:
[26-Nov-2013 10:41:19] StoreRewardPoints called but SESSION['REWARD_POINTS_EARNED'] not found

I am on Zen-Cart 1.5.1 Latest rewards points module. It was working great. Not sure what happened. I have reinstalled a fresh copy overwriting the files. I have tried reinstalling from my backup site. Both have not fixed the problem. They did change the error log from:
[25-Nov-2013 22:54:49] PHP Fatal error: 1064:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND status=0 ORDER BY date DESC LIMIT 12' at line 1 :: SELECT rewards_id, orders_id, date, reward_points, status FROM zen_reward_status_track WHERE customers_id= AND status=0 ORDER BY date DESC LIMIT 12; in /home4/w57dsjmm/public_html/order/includes/classes/db/mysql/query_factory.php on line 120

But just to be clear my current error log is:
[26-Nov-2013 10:41:19] StoreRewardPoints called but SESSION['REWARD_POINTS_EARNED'] not found

Thank for the help. It worked great since October 10th. So I started advertising it yesterday. Of course it stopped working hours later.
