After a hard reset of the PC (power blackout) , the wallet doesn't work when I run it normally , using the same password as always. I get: 09:36:59 2016-02-27 [ERR] DCRW: invalid passphrase for master public key So I was playing with it to make it work, and I tried without putting any wallet passphrase (except the dcrd u/p)... and it works! I'm really puzzled by this. What gives? EDIT: Additional info: I was Stake mining before the rest.
