TN Express Error Message

I've just set up some promo codes which have a limit on the number of seats a customer can purchase (x3)

The codes all work fine, but if a customer selects more than the allowed number they are currently getting the error message "It seems these seats have been taken, please try again"  <continue>"

(This is the same text I get if an empty seat is left in between seats selected) 

I need to edit this text to say something more accurate "too many seats selected for current offer" or similar

I've looked in LTR_TN_Express_Web settings / cart settings / etc - all of those and also documentation here at the Network but can't find reference to this particular phrase.

Does anyone know where this particular text lives in the system tables?
