You are mining successfully! Note that the UniMining site says:

Payouts are made automatically every 2 hours for all balances above 0.01, or 0.001 on Sunday.
For some coins, there is an initial delay before the first payout, please wait at least 6 hours before asking for support.

So you need to mine 0.01 Lux before that mining pool will make a deposit to your address.

As with most cryptocurrencies, the amount in your address is determined by the distributed blockchain. Your wallet software is simply querying that blockchain. You don't need to run the wallet in order for the mining pool site to make a deposit. You would use the wallet either for staking or for spending the coins. You should encrypt the wallet. Check the menus (at the bottom).

I'm not sure about your last question with the errors. There you seem to be mining to a different pool, xmr.suprnova.cc.

Regarding the part I bolded, do you have your actual address there? It needs to be there. And I don't think quotes are needed around it.

Since you are mining at unimining.net, you can check the progress here (enter your address):

Good luck!
