I am testing out some scenarios with micro payments, for instance sending 0 fee micro-transactions. I sent one for $0.01 and one for $1.00 both with 0 fees. Now, I can no longer send from that wallet address, even though I have .14 BTC in the wallet. I get a message:
"This transaction cannot be sent because there are insufficent funds available. This may be due to additional miners fees or unconfirmed transactions.
The transaction can either be cancelled. Or the amount to send can be adjusted to match the maximum amount available to send."
So, my 2 unconfirmed transactions are stuck in there, which are causing this.
It is likely that your tx will never be confirmed. If you stop re-broadcasting the tx, it will be dropped by all the nodes after a day or so, and you will return back to your original situation before creating the those two tx.
