Hi there. Just found ERC and wanted to try mining some on the suprnova pool, but I can't seem to get minerd/cpuminer working (yes I am a noob at this so all help is appreciated).
Basically I downloaded the v3 wallet and synced it, but now I'm not sure what to type in the .bat file in the minerd/cpuminer folder. Currently I have:

minerd.exe stratum+tcp://erc.suprnova.cc:7674 -u username -p password

(username and password are changed to my username/password)
When I start the miner, the window pops up for 2 seconds then disappears.

Do I need to add a europecoin.conf file to the Roaming/europecoin folder?

EDIT: I downloaded cpuminer-opt from the ERC mining guide and tried running the ERC_START.bat.... this one gets a bit further before crashing. It gives me an "unsupported CPU or SW configuration, miner will likely crash!" error, then tries to start but crashes.

I have an i7 930 cpu, running Windows 10
