Guys, you should update the wallets to the latest version. This is a compulsory update, otherwise you will not be able to use your coins. Also the collateral to make MN is 10000 coins now. Follow the steps: 1. Copy paste the wallet.dat file somewhere safe and then delete the entire Harvest folder. 2. Install the new wallet from the below link for wallets: https://github.com/HarvestMasternodecoin/HarvestCore/releases 3. You might see warning messages, click OK and proceed, once the wallet syncs, you can close wallet and then replace the wallet.dat with the old backed up wallet.dat file 4. Restart wallet to see your previous balance. 5. There will be some lost coins as we rolled back the chain to 15th June to get people back on single blockchain instead of the multiple blockchains they were on.
