First step is to download the new HUZU wallet version 184.108.40.206
Once you have downloaded this wallet you can delete the old version. Just remember not to touch the data folder (always remember to backup wallet.dat).
Open the new wallet and let it load. Once loaded please click on Tools / Wallet Repair.
After the wallet has reloaded and synced double check you are past block 4999. If you are still having issue please ask for help in the #wallet-general channel on our discord.
