My BTC wallet was
bitcoin core ver. 0.12.1
After sending my BTC to another address, and waiting for two days status was 0 confirmation, maybe be because the transaction fee was not enough,
So I found a solution from google,
-salvagewallet, then it seemed to work
But today I try to send my BTC again, after I insert my pass-phrase, a window show up which says
assertion failed program:C:\........bitcore-qt.exe file:wallet/crypter.cpp,line 190 expression: false
if click ignore button, it says pass-phrase incorrect.
if click retry, it says runtime error.
don't know how to solve this problem
