Thanks for the tip, I am about to give this a try!

QQ: If I go ahead and remove those unconfirmed transactions, which is the whole balance of the wallet, how will the offline wallet be able to verify anything afterwards? It couldn't find the inputs on the previous attempt to sign, so it's counter intuitive to me, to remove the limited data I do have (the unconfirmed transactions) would that force the offline wallet to use the inputs from the raw transaction? If that's the idea I'll give it a try.

Thanks again for the help and the lead to the documentation which is helpful but very technical!
