Thanks for your reply.
I have a couple of questions for you but I will ask one at a time. From miningpoolhub.com they gave me the above command line for the Expanse pool. I am not sure what is going on with this part of the line: -dpool stratum+tcp://hub.miningpoolhub.com:20550 -dwal username.worker2 -dpsw x -dcoin sc
I never see any silacoin appear in my mining. What is this part of the command line for? Do I really need it?
Since you are using Claymore Dual in the config and there is a second coin. In this case, Sia, but could be Decred.
Example:

If you want to extract only Expanse then delete this part of the line
-dpool stratum+tcp://hub.miningpoolhub.com:20550 -dwal username.worker2 -dpsw x -dcoin scDid you specify the address of your Expanse wallet on the pool?
