All my mining stopped. When I stopped today and restarted. It says no server were found that could be used to get work from . Please check the details from the list below of the servers you input. Most likely you have input the wrong URL, forgotten to add a port. I am using this batch files for months.
One thing I noticed which ever running it is mining. If I stop that restart it won't start mining. URL I am using startum+tcp://ltc.give-me-coins.com:3333 user:ddddd Password: ffff
