cs-cart Bug of a cloned website

i have a bug for cs-cart. I have imported promotions from database... old cs cart to new one... .but promotions not working.. if you create NEW promotion it works perfect.... so i suppose it might have diffrent structure old database to new one... thats why i ask for someone familiar with cs cart versions if you have face this problem again.... i was thinking if i create new promotion (same as another one) and go to database and see if there are diffrences...i have 282 promotions with multiple categories and products and i cannot make them from beggining!!! so...i want to know how much for it...and if we are ok we can continue with other projects too...i am developer...i have [login to view URL] company...and i need some times developers to solve such problems...this one is small one...i can figure out but need time...so if you can do it it would be good...and also to continue work with other projects too... thnx
