I done the same b3coin.conf thing on my windows laptop, it got the wallet to sync but my coins have vanished

?
how did you get yours to sync? i did the b3coin.conf thing, and it made zero difference. I have 100$ of coins supposedly coming to my wallet and i think i just lost it all. Not happy.
Always keep a safe copy of your B3COIN APPDATA file in a safe location before doing anything with your wallet, so that you can revert to previous settings if anything goes wrong.
