Need to keep Firebird running

I use a Sam Broadcaster Pro to DJ and need Firebird to always run in the background how do I get it back to that

Ar you saying that you have you put it to sleep in Performance Optimiser?
(That might have been done in Health Check which also runs the PO).

If so then open the Performance Optimiser, look for it in ‘Sleeping Apps’ and wake it up again, then set PO to ‘Exclude’ it so that it won’t put it back to sleep again.
