just installed Reward Points and all works fine, BUT...
after setting up Paypal Express checkout i get the following error after clicking the Express button when not logged in:

[FONT="Courier New"]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 ((prp.scope_id= AND prp.scope=4) OR (gp.group_id=c.customers_group_prici' at line 5
in:
[SELECT redeem_ratio FROM zen_reward_master prp, zen_customers as c LEFT JOIN(zen_group_pricing as gp) ON (gp.group_id=c.customers_group_pricing) WHERE c.customers_id= AND ((prp.scope_id= AND prp.scope=4) OR (gp.group_id=c.customers_group_pricing AND prp.scope_id=gp.group_id AND scope=3) OR (prp.scope=0)) ORDER BY prp.scope DESC LIMIT 1;]

is if there is a way to fix this problem...?
