Missing Bits

I'm not sure if this is the right place for this, or if it should be considered a graphics issue, but here it it...

I recently installed the Alabeo's Diamond DA42 'Twin Star' for FSX. All went well (I thought) until I loaded the aircraft for a flight. The interior views looked as well as expected but when I went to an external view, much of the plane was missing. I have had this happen with another aircraft as well but can't remember which one. Backing out of flight mode and changing to a different livery did not correct the problem and when I went to internal views, most of the panel was now missing as well.

If this is some odd glitch or a setting I should change any help would be appreciated.

Of note may be the fact that this was an installation of V2.0 after removing V1.0 which had never had any problems.
