"Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database." can you translate please?
That message means that blockchain.info has removed the transaction from their node. This does not mean that it cannot confirm, nor does it mean that every other node on the network has also removed the transaction.
When you did "Repair Wallet", did it remove the transaction from your wallet (it should have)? Did the transaction appear again after some time, or did it never leave your wallet?
