Hey guys, im pretty new to this crypto business. When i open the windows wallet, it says out of sync, and it doesnt do anything.  Is there something i need to do with the .conf file to start the sync? Sorry these are noob questions.  Been storing on exchange, but Id like to start keeping them in my own wallet.  Any help will be appreciated.  Ill be holding on to the few KNC I have for a long long time.
