Thanks for the reply. I mine to the address of the wallet that appeared in my personal account. A month ago, payments on it stopped.

Hi,
Mining from the pool to the pool is not really supported. Please mine to your home wallet address.
Also, please don't mine to SouthXChange either; a lot of services do not receive coinbase payments that are sent as multi-v-out-s (like we send from the pool). You can mine to 'unchained.biblepay.org' if you want, but that program is in beta, so I still really recommend to mine to the home wallet.
Let me know how much you missed and I can give you a pool balance credit.
Thanks.
