. Been successfully mining in a pool for almost a week now. For the past few days, I have been attempting to solo GPU mine. Has something been changed recently? I can read posts from earlier this year on setting up the config file and also the miner .bat file. Can not get it to start at all. Command prompt window opens and then either crashes, or says 404 error URL not found. Any advice? Just thought I would do a small test to learn solo. Thanks everyone! Hopefully I posted this in the right place.
