Is this a c++ runtime error you're experiencing on startup?


Check your gridcoinresearch.conf file, if it's empty or corrupt please fix it. If it's fine, then your blockchain is corrupt & you must delete all gridcoinresearch appdata files EXCEPT FROM 'wallet.dat', 'walletbackups' and 'gridcoinresearch.conf' then resync the blockchain (either via snapshot, download blocks or slow natural sync).
