Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics
Yes I login many times today. I also use a yubikey. It shows error decrypting password. I made a test wallet and login fine.
Might be an issue with auto-detection between old and new wallet formats. Please try again now.
Edit: Also next time you login please run the "Integrity Check" found in the Account Details tab.
Cool, but it says "0 BTC received" 
fixed.
