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.
I try to delete blockindexes.dat and blocks.dat.
But my wallet coin amount is not correct.
The pool.jimcoin.net display more than my wallet.
I don't know what happened
Stats on the pool are a little messed up right now and a lot of orphaned blocks need to be re-mined since the pool was mining on the wrong fork for a while. As long as your wallet syncs to the same block height the block explorer you are on the right chain.
