Many thanks for the reply.
I was able to do the reward assignment. But I still keep getting this under "start mining"

Anyway, I have gone ahead and pressed Start Mining (Default) option.

It has initiated the mining process. I can see the following on the miner window

Does it mean it is working as it should even though I am consistently getting the ErrorCode 5 issue?

Sorry about all the additional questions.

I am looking forward to a reply.

Thanks a lot.

Kind regards
