Try new version download from github, it seems works but pool for devfee not always ethermine.
what do you mean mining solo mode on ethermine?
Nothing special. I meant I dont mine 2nd coin, but it should not matter. My bat for example is : nodevfee.exe EthDcrMiner64.exe -epool eu2.ethermine.org:4444 -ewal 0xcb4effdeb46479caa0fef5f5e3569e4852f753a2.worker1 -epsw x -r 1
Try experimental version it is meant to fix pool switch problem, but I cant really test, cause havent noticed mine switch pools.
You should see NoDevFee: connect -> message in console if connection is being redirected.
I try experimental version, I see this in my console :
DevFee:ETH Stratum-connecting to 'eth-eu.dwarfpool.com' (87.98.182.61) port 8008
NoDevfee:connect ->asia1.ethermine.org:4444
NoDevFee:eth_submitLogin->0xxxxxxx
DevFee:ETH Stratum-connected (eth-eu.dwarfpool.com:8008)
ETH:Authorized
DevFee: start mining
DevFee: ETH 11/02/17-16:43:11 - New job from eth-eu.dwarfpool.com:8008
ETH: 11/02/17-16:43:11 - New job from asia1.ethermine.org:4444
ETH - Total Speed.................
DevFee: ETH 11/02/17-16:43:21 - New job from eth-eu.dwarfpool.com:8008

Does it work?
Then below you will still see the miner thinks its mining to its own dev pool/wallet but in fact its now been replaced with yours. Check your pool statistic page and you will see the additional miner called default and its few recovered shares per hour.
