"Unable to find all tx inputs"
If I'm reading correctly, your input transaction is  7bd31512076520e5fb2ee1cef9b6e63f0571cbd05d26676c7df336b4e0323e3f.  This transaction is not found by a search on blockchain.info.  I would guess one of the following is true:


The transaction id is incorrect
The transaction was never broadcast
The transaction was broadcast, but was never confirmed, and so much time has passed that  blockchain.info stopped keeping track of it.


So, check that the id is correct, and if it is, try (re)broadcasting the transaction.
