The newest version of the miner doesn't read the config files as it used to.
I have copied over the old one that worked with the previous version just fine and now it just ignores it.

update : in the start_miner.bat file there are these 3 lines
"REM IMPORTANT: Replace the ETH address with your own ETH wallet address in the -wal option (Rig001 is the name of the rig)
PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal 0x008c26f3a2Ca8bdC11e5891e0278c9436B6F5d1E.Rig001
pause"

if you delete the bold part, it will read your config files
