Dashboard Won't Run

[MattG 0]

I don't often log into the server as it does it's job backing up and storing files just fine.  Seems to continue doing that. But when I try to start the server Dashboard from a client, the screen comes up and says "logging out...".  When I try to start the Dashboard on the server itself, it just simply won't come up.

I tried restoring from the earliest backup I have but the issue is still there, so I don't know how long this has been a problem.  At least two months it seems.

 

Is there a way to reinstall the Dashboard?
