So I thought I had a pretty good grasp on this whole bitcoin thing. But as it turns out, I guess I don't. I made a couple of "offline" wallets with bitcoin-qt on Ubuntu 12.04.1 LTS using usb drives as a virtual OS. So I made 2 wallets, populated 10 received addresses for each wallet, then saved out the wallet.dat files to another usb drive. So I've been using the addresses to get some free coins from the free bitcoin sites. After a couple of weeks I decided to sync these wallets just to see if things were going as I thought they should. Once I load them, and they are synced, neither of the wallets show any transactions. They both have the addresses I had originally made, so it doesn't seem like the wallet.dat files are bad, or that I messed up backing them up. Perhaps I did and just don't know. Anyway, so I looked up the addresses on blockchain.info and found that transactions had been made with the addresses used.
Here are 2 of the addresses if you'd like to check it out yourselves. Any help would be appreciated. Let me know if anymore info is needed. Thanks!
