I can't seem to get 4.6b to run. I have a mixed rig with Polaris and Navi and the miner just closes and/or crashes immediately. I just get the intro/version line then it exits.
Phoenixminer.exe -mode 1 -gsi 30 -amd -pool naw-eth.hiveon.net:4444 -wal WALLET -pass x
Phoenix Miner 4.6b Windows/msvc - Release build
-----------------------------------------------
Then returns to command line after that.
