I got the stack trace if you need it.
In the meantime, I can do another account, yes, but I already received my 0.5 BTS on this old account.
Can I receive 0.5 again for my new account ? BTSX8D2hhVwZSDzg6eYnGLZQvPfnYbF98Herwe1wLEUr8MRqSqubaG
Edit: nevermind, I just received 0.5 BTS from onceuponatime. Thanks !
