Module not working right

Hello,

First of all, I'd like to say this is a great module and I think it could be very useful for my webshop.

Secondly, I have to tell it doesn't work as it should for me... I followed the steps as described, but the sponsor user never receives a discount. Instead, after the new user's order status passes to complete, the amount of THAT order gets decreased by the sponsor value (€10 in this case).

So after all, nobody has got any profit from it...The new user already paid his order and then gets a discount, and the Sponsor user never gets a discount at all...

I hope somebody could help me with this, 'cause I really like the concept of this module!

Thanks in advance!
