get Armory to use an existing blockchain? I'm trying to set up Armory but it wants to download the whole blockchain.  The thing is I already have the blockchain downloaded on the same machine for bitcoin-qt.  Is there any way to get Armory to use the blockchain I already have, both to save space and avoid waiting for hours?
If your settings are correct, try restarting Armory, and let it run for a few minutes. I had the same concern thinking that Armory was redownloading the blockchain, but it was actually reading from the harddrive (Listen to the harddrive).

After roughly 10 minutes, the block synchronisation went from 0% very quickly to 100%, then the status changed to "Connected". Next Armory synced the transaction history for another 10 to 15 mins.

I guess there is a user experience bug here. Armory should have had a user friendly message somewhere saying something like: "Verifying local blockchain".
