Looks like I had a similar experience to the poster below. Digging through my hard drive, I had two versions of the preference pane installed it seems. The older one, (v2.1.3) was the version being used, but when I went to the about box it would strangely show up as 2.2.0.49 hence the confusion. Looks like their installer isn't very thorough when deleting and upgrading the proper files.

I apologize sincerely, but they should take their share of the blame.
