Winlogbeat Dashboard

Can anyone help me get my dashboard working again. I deleted an index ( winlog 7.1.12.0) and a new one got made (winlog 7.1.12.1) but now I get loads of errors when using the built-in dashboard

I'm not sure where to start (apart from wiping the server and starting from scratch)

good news. I stopped winlogbeat on all my Windows Server DC's. Then I deleted the winlogbeat index under /data/Index Management. I then ran winlogbeat setup -e on all my Windows Servers again and started the winlogbeat service on the Windows Servers. Dashboard is now working again.
