I deleted the files in the roaming folder and re installed.   The wallet proceeded to d/l the blockchain but stopped about 10 hours shy of snycing. I shut the client down and tried to reopen it but the same error  comes up. Is anyone else having this issue? 

I was checking on my lts letting the wallet  sync to see when the shares would be minted and now I receive:failed to connect best block and the program shuts down.
Any advice on what I should do next? I have claimed my shares but they have not been minted yet. I am assuming that as long as I import my private keys again my shares will show up during re installation.
