XPOI doesn't came bundled with anything, you probably installed the Trial long ago and forgot about it.
The problem ( judging from your screenshot ), is that you enabled ALL categories ( by default they are not all enabled ) and in that particular area there were probably too many points to display, so the simulator couldn't keep it up with all of them.
That's why by default XPOI doesn't come configured with all its categories enabled, you must have opened its settings and turn them all on, but since you might have done a while ago, you might have forgotten about it, same as you forgot to have installed it in the past.
