ROFL! That's the my sentiments exactly. So here is the non-intuitive procedure:
-cancel your registration (this will get the $75 charge out of your cart)
-go to your memberships and join the SWDivisional series
-go to your garage and create a new car (that's the same as the one your are already using) that is linked to your new SWDivisional membership
-go register for the event again, this time with the new car
See wasn't that easy! :confused:
