Bug report for BitKoot wallet linked at Meanwhile I did another update (https://dl.dropboxusercontent.com/u/6522303/CryptoNoteWallet_latest.zip).

It does not support wallets created by CryptoNote Easy Miner 0.03, unless you rename the walletfile to walletfile.dat. (and the keys file too)
Please fix in next version.

(Sent a PM too)

/EDIT Not created by EasyMiner, but incorrectly named by myself, when generating the wallet and not adding the .bin to the walletname...
