[Quitch]

Restarting the services (in the recommended order... just to show I know something ;)) seems to have done the trick.

Thanks for the assistance, chaps. Have to say, this is one of the more helpful and supportive forums I've been to.

EDIT: Spoke too soon (about working), I thought it had ticked it but that was another message sent by the user which appeared at just the right time to inspire hope. Guess I'll try the longer downtime and double-check all the permissions.
