Unknown column 'c.params' in 'field list'

We just finished work on a development site and moved it into web root. AWO Coupon isn't working.

I put Joomla in debug mode and tried to access AWO Coupon in Admin and got the following 500 Error:

I checked a previous install of AWO Coupon and there isn't a single table I can find with the column params so I'm stumped.

JDatabaseMySQL::query: 1054 - Unknown column 'c.params' in 'field list' SQL=SELECT c.id,c.coupon_code,c.num_of_uses_type,c.num_of_uses,c.coupon_value_type, c.coupon_value,c.coupon_value_def,c.function_type2,function_type2_mode, c.min_value,c.discount_type,c.user_type,c.function_type,c.startdate,c.expiration,c.order_id,c.published, 0 as usercount,0 as productcount,0 as categorycount,0 as manufacturercount, 0 as vendorcount,0 as shippingcount,c.exclude_special,c.exclude_giftcert,c.note, c.parent_type,0 as parentcount,c.params FROM jos_awocoupon c GROUP BY c.id ORDER BY c.coupon_code LIMIT 0, 20

TIA

I had installed a new version on the dev site but was dropping the tables and importing data from the old site running a previous version of AWO Coupon.

The new version apparently has a field for params so I created one and it now works.
