1. Backup your wallet.dat and gridcoinresearch.conf to somewhere safe. (For windows go to your search bar, type %appdata% and press enter, then navigate to Roaming and then the GridcoinResearch folder. For linux, go to ~/.GridcoinResearch)
2. Go to https://gridcoin.us and get the latest version of the wallet for your system
3. Follow the prompts for installation
4. Load up the new wallet and it should work right out of the box!
