i was mining with a pool and kept getting kicked off with those disconnect errors.
im also not sure when a coin in actually mined.
it kept showing block after block on the command prompt box, and after the first 12 hours I got 44/44 agree lines
but i haven't been doing it long enough to know what any of that means, lol.
when i get the other laptop up and running i will see if i am able to mine with no errors.
When you are in a mining pool, they usually have a minimum amount before payout. No errors is always a good sign
