With absolute the same settings as before, I got this error:
This is just a warning, the miner is trying to set zero memory offset to avoid DAG corruption and fails because it lacks admin privileges, you can ignore it.
Also pool hashrate is too small, even acceptes shares is small too (26 accepted shares after 7 minutes of mining), compairing to Gminer wich does 41 accepted shares after same 7 minutes of mining;
So?
26 or 41 shares are very small numbers, you need to find thousands to get a good estimate of how well the miner is performing, see
