No one is currently able access our ServiceDesk Plus MSP system because the Services on the Server have stopped.

I have connected to the server and tried starting the Services.  They sometimes start, but before I can access the portal the services stop again.

Any advice on what I can try to get our system working again?  The installation is on a Virtual Machine hosted elsewhere.  We are running version 8.3 8301 (I think - can't access currently to confirm).
