I am trying to use oclvanitygen to generate some LTC addresses by using:
oclvanitygen.exe -X 48 Litesomething
(I used information on
https://en.bitcoin.it/wiki/Vanitygen , -k switch doesn't work though)
but on the LTC console, importprivkey command always gives this error message:
Error adding key to wallet (code -4)
-4 supposedly is insufficient fund error, should be irrelevant here. (the wallet does have some coins).
Did I do something wrong?
