I have the same issue with the coins not arriving when importing the key.

my key contains no spaces, is 52 characters long, the wallet is fully synced and the wallet isnt encrypted (its a fresh install, will encrypt when the coins are back)

How long is the import supposed to take? I left it for 3 hours but nothing has happened. I restarted the wallet and the new payment address was there but no coins?

anyone know what might be happening? (did i need to leave it longer than 3 hours?)

Any advice would be greatly received.
