Error Message displayed

[CloudWarrior]

Evening All.
   This error message has appeared om my screen while running Basestation.
It doesn't stop Basestation running, but I cant clear it so have ended up dragging it down to the bottom of the screen.
   I cannot recall me doing anything out of the ordinary prior to the message. 
   Any ideas what this could mean?

I've attached a screenshot.

This typically appears when you either have too many files in the OperatorFlag folder or a corrupt one.  Have you checked the files using BMPCHK?

I will give the checker a go.
Thanks.
