SPIKE-LORENZO  I checked this zip code, 05641 and I get a forecast for this location. Can you and the others go to http://www.spikesoft.net/support and send a support email detailing the steps you took and any error dialogs reported by Weather Vane. Be sure to include the version of the OS (10.4.x or 10.5.x) and we will investigate the problem.

Thanks, and sorry for the inconvenience.

SPIKE-LORENZO  What zip codes are you using? If there is a problem with the zip, you should get an error. Otherwise, they may be something else going on.
