Heya Statusplayer,
Welcome to SimV!
Just to let you know--It's not your fault!! Taking your suggestion I downloaded and installed this aircraft myself. My experience in Flight Simulator started even before Microsoft bought out the title (Yes, I'm an old coot!)
I read through the install instructions and discovered that it was pretty much straightforward. The author even supplied all of the necessary modules files.
The big problem is that there are a couple of *.xml and gauge files which are either corrupted or improperly compiled (the most notable being the ILH_TCAS.gau file). It seems that these gauge files cause a fatal exception error which drops your FS 2004 to the desktop when you select this aircraft.
The way I see it there are four ways around this issue:
1.) You can check here or on other websites to see if the author has come out with a better panel
2.) You may try and remove the offending gauges, replacing them with default gauges
3.) You can delete the lscc2_9 Panel and Copy/Paste another panel in its place (i.e. Lear 45 panel)
4.) You may check around SimV or other websites for a better panel
Personally I favor suggestion #3 myself. It's the easiest by far. Now if you want a panel that has some interior views, I recommend this file:

Voila! Problem resolved.
