Wallet didn't work for me.
Was an easy fix:
copy GrumpyCoin.conf to %APPDATA%/GrumpyCoin
What about MAC wallet ? My doesnt work .. I copy .conf to appdata ...
My mac wallet is working fine. Here's what I did a couple weeks ago to fix it.
Click on Finder, then 'Go' up at the top, hold the alt/option key and 'Library' will appear, click 'Library'.
Go into 'Application Support', then 'GrumpyCoin'. Drag the Grumpycoin.conf into the GrumpyCoin folder.
Launch/Relaunch wallet and it should begin to sync. Down the road we shouldn't have this issue as more people start using the wallet. Let me know that this works.
