Yes I'm using bitcoin-qt, and the transaction still show there in my transaction history and the total amount of bitcoins remains correct, its just the address that dont appear in the address list to receive bitcoins and I think thats what causing trouble with the import to blockchain.info. I think the best solution is to transfer all bitcoins to a new wallet just in case to avoid any trouble with that transaction, I will try it later today and see how it goes (cross fingers ^^).

Thx for your replies
