I have 2 storages.

I don't have a Storage ID=2 and this message keep appearing to me, a lot really.

Storage ID Error
Re: Storage ID Error
You either have events that were on storage area 2, or a monitor that is assigned to storage 2. Deleting a storage area record unfortunately does not invalidate existing events/monitors.
