minimwatch thinks it's already running

[adrian]

I invoked minimwatch under linux and got this:

Code:

adrian> minimwatch
MinimWatch 0.8.4, Copyright (c) 2012-2016 Simon Nash. All rights reserved.
Enter command (? for help):
>MinimWatch: can't run multiple instances with the same configuration file     Selected media server: MinimWatch
MinimWatch failure: now stopped, use 'relaunch' or 'exit'

even though I don't have any other minimwatches running. (I just rebooted.) Is there a lock file somewhere I need to delete?
