i have ver. 1.1.5.5 GRC client, i was mining the whole day and found a block then when i woke up my miner say " not responding" and found out the client close by it self so i re open the client and its not synchronizing properly so what i did is uninstall the client, delete the gridcoin folder, delete the blocks and chainstate folder as well as the peers.dat files and reistall the grc client but still unlucky to synchronize it, so i have no choice but to restart my computer and when i re-run the client again it says "Warning Displayed transaction may not be correct! you may need to upgrade or node need to be upgrade" i don't know what to do now? any solution? Thanks
