Yesterday I tried to start mining PTS on ypool. I changed coin mode to PTS, downloaded an optimized jhprotominer and started it. It looked like everything is OK. The miner was working, finding shares. Most of shares were accepted. But I didn't see anything in my account in the pool. No connected miners, no accepted shares, no unconfirmed rewards. After several hours of mining and finding more than 100 shares I stopped mining.
I tried to deliberately change the port to see what happens, if I choose a wrong port the miner reports that it can't connect to the pool.
Some time ago I successfully mined some XPM at this pool.

Could somebody explain what i'm doing wrong?

Edit: it started working for me after removing -m512 parameter.
