PhoenixMiner 5.4c is officially released. You can find the download link and the checksums in the first post of this thread.
It is the same release as the one that was posted yesterday, so if you are already running it, there is no need to upgrade.
I have the Windows 8.1 and AMD driver 16.9.2 and R9 390. I tried to run 5.4c on the ETH network, still have the -61 error.
