try deleting the peers3 folder.
it keeps the database of your known peers, but the node will find new ones as soon as it's up.
Thanks, it seems to be working again!
Maybe it would be a good addition to auto delete or re-generate this file or dir if it's corrupt or missing? That way, if this situation would ever occur for some reason, Gocoin can still continue.
It's just never happened to me that this DB would get corrupt.
If you can find a way to reproduce the issue, I can investigate then and find the best fix for the problem.
