We have installed UPS module for shipping and when we go to Step 1 of the checkout process we are getting this message.

"United Parcel Service (XML)
111286: Ontario is not a valid state for the specified shipment.
If you prefer to use ups as your shipping method, please contact"


When we do a shipping quote, everything works okay. I checked the UPS Module and it is active, green light is on. We are currently using Zencart v1.3.9b

Any help would be great!

Thanks.
