Has anyone got this extension to work with 1.30?  Installed the extension as per the instructions but for v1.30

When trying to add any item to the cart, I get the following error at line 124 in the file

FixedpriceShippingByCountryComputationMethod.cs


  decimal? IShippingRateComputationMethod.GetFixedRate(ShipmentPackage ShipmentPackage)         
       {
            throw new NotImplementedException();
       }



Error details below:  Anyone got any ideas??
