WIF = "Active, private Key"
Just go into your permissions, go to the second entry where it says "Active" and unlock the Active private key by klicking "login to show" on the right. This key should indeed start with a 5.
I have set up my computer to mine both on linux and windows multiple times. I'm sure we'll get this sorted out! If you want some quick help, I suggest going to the #mining Steemit chat here: https://steemit.chat/channel/mining
There are plenty of experienced people that want to help :)
