Google Checkout all of the sudden not working...

I don't know why... but all of the sudden when a customer goes to checkout via google checkout it says, "Midwest Appliance Parts does not ship to this address via Google Checkout"

this has been working 100% fine since we ever installed it, now all of the sudden this error is happening, any ideas?

ps - this happened right after our server had to restore a backup....

actually this happened after the restore when recently we
had to fix a nameserver issue from our host. since then when anyone tries to checkout, even my personal account from the USA, it says:
Midwest Appliance Parts does not ship to this address via Google
Checkout

Is there some kind of allowed IP for transactions?

Any ideas? I really need to get this fixed... we use Zen Cart.

This is sooo frustrating!

thanks for anyone who responds

Did you resolve this???
