Inbound lines ring engaged...(callerid module auto disabled)

inbound lines ring engaged… and i discover that callerid module is “disabled pending upgrade”.

what on earth could i have done to cause a module to become disabled and effectively bring the half the system down …

I do have fpbx set to advise of upgrades but advise is all it should do (?)

seems ok now but really don’t want a repeat - any ideas?

thanks
