Two more questions

I am running 2 Win10 machines without GPU's. Each machine has installed the BBP wallet and the BOINC client. I am receiving regular PODC rewards but several days ago both wallets stopped mining (0% CPU activity and no rewards in 8 days). Here is the config file for the 1st machine:
addnode=explorer.biblepay.org
genproclimit=2
gen=1
externalpurse=BQ5epKDHsp9AWjVgRYd9ZysQa7g75ve539
externalprivkeyBQ5epKDH=[my_private_key]
externalpubkeyBQ5epKDH=BQ5epKDHsp9AWjVgRYd9ZysQa7g75ve539
1. Is the config file okay?
2. Should the config file for the wallet on the 2nd machine be identical (for PODC purposes) or reflect the CPK of that wallet?
Thanks!
