As was mentioned in the other thread, your transaction is dependent on this transaction: https://blockchain.info/tx/152a65239eec41036614612be23f124f9ef861b30b521c57c9ff12c8c773b792 confirming. Is this transaction sent by you? If so, then there are solutions, otherwise, there is really nothing you can do.

That error means that the fee was too low or the transaction was unconfirmed for too long that blockchain.info decided to remove the transaction from their database. This does not mean that it was dropped from the network. Also, it appears that the transaction you mentioned in the other thread is still on the network.
