Stoneedge and ShipRush Setup

Trying to get Stoneedge Order Manager to work with ShipRush.

I've been thru and set what i believe are all the Stoneedge parameters.

However, when I go to print a Fedex label a box pops up and says "System Parameter Not Set - Cannot use FX shipping."

I have no clue what parameter is not set, it doesn't say.

Are the Sysops or is someone else versed on ShipRush and Stoneedge?

Thanks!
