Hey! I got it.
The domain was still registered, and yes it was shippingworldwide.us
The problem was that even though I changed the servernames, when I checked them again 1 hour again they were different =S, they weren't even the old server's names, just something random (can't explain why)... but anyways, I changed them again and now the site works.
Thank you SO SO much for the quick responses!
