I have been having some issues with bit-qt corrupting and having to rebuild the blockchain, and in the interim my armory funds are locked up and can't be accessed.  I have the back up, but the "seed" armory uses seems to be unique to Armory.  I have the private keys/addresses but trying to use Electrum and sweep them doesn't work, nor does the import feature in blockchain.info (granted I could be doing it incorrectly as I have never had to do this).

What is the best way to get funds out of an armory wallet, with an alternate client?
