I have released a new version of the TkWallet which improves the process. As a result, you must now run "StartTkWallet.cmd" instead of "tkwallet.exe", that is all.
This is my walletd.log file:

He writes something about the bad version of the wallet. But with my wallet file, I can easily mining in cmd mode and this work.
I have no idea why that error occurs.
