Alright, I usually do stuff the way it's intended to be done - it saves time. But if this works, I guess I'll keep using it... (I was still using an old wallet until today).
If you want to mine with external miner,you need to update your wallet.
There is also another "if" - if your external miner is AMD. Because the nvidia miner hasn't been updated and did not have any problems with the old wallet.
I will publish a new wallet without the dev fund, block reward: 5 TAC, all fees will really be destroyed in the genesis block and with some new features that I am developping.
