I need your help because i have this message now after clicking on "Refresh wallet" : You cannot forge because your account has no public key. Please make an outgoing transaction first.
For forging you need a public key, mine some DIRA through Brain/CPU mining, after that make a transaction (even to your same address) of 1 DIRA so you obtain a public key.
Why does it says Java not installed when I just installed it?
Did you try to start run.bat inside DIRA subfolder?
