I cleared the shadow folder and got the blockchain downloaded. Wallet says up-to-date now but now all my stakes have been mined but not accepted. Any others having issues?
Check you have the most recent client, the latest is version: 1.4.0.3
If you need to get the latest download you can get it from
https://shadow.cash (do not download directly from links on this forum as they may be replaced with viruses)
