OK so at this point we have 2 chains going, if you have a block height higher than the block explorer be.jimcoin.net you need to delete your blockchain and sync from scratch.  On windows close your wallet and search %appdata% in your search bar and delete blockindexes.dat and blocks.dat from the JimCoin folder then open wallet again.  On linux, close your wallet and navigate to the .JimCoin folder in your root directory and delete blockchainindices.dat  blockscache.dat blockindexes.dat       and blocks.dat then re-start wallet.  Once done we should all be on the same chain matching the block explorer.
