If you paste the contents of your debug.log file we can take a look at the issue, otherwise you can try this: - Close your wallet - Next, go to search and type %appdata% , you will see a folder called Jincoin. Go in and delete the folders called "blocks" and "chainstate". DO NOT DELETE your wallet.dat - Download the latest wallet from https://github.com/jincoin/jincoin-core/releases/download/v2.0.2/jincoin-qt-2.0.2.1_x64Windows.zip - Run it and let me know if everything synced up.
