Maybe the best way to fix this is to delete everything in the MAY folder in appdata-roaming, back up the wallet.dat first. Delete everything except for the wallet.dat and let the wallet re-sync from the start again. It might take a couple of hours but hopefully this fixes your issue as I have also had this issue in the past with MAY but that was caused to the power going out which then gave me an error so I just re-synced it from the start and all was well again. Remember to not delete the wallet.dat file or you will lose your coins and be sure to back up the wallet.dat before deleting anything. Good luck!
- Thank you! It helps me!
You're welcome my friend, I'm happy to hear that this has helped you out and you can get back to staking MAY again.
I'm not sure if the dev comes on this thread but I do think we need to look at other options for more pairings for MAY, Coinexchange have other pairings but not sure what the cost is. I'll be surprised if the price can hold above 1 sats once the 1k block rewards start.
