Star Render and crash in editor

This is in the Getting Started area because I'm new to TGE, and not sure how to troubleshoot some things. Any help you can give would be appreciated! :-)

I successfully added the Sky Sphere code to TGE and have it working in a mission. I then integrated the Star Render code, and the mission loads just fine. When I click on the Media for the sky, however, TGE crashes. There's nothing in the log to indicate what it's choking on.

I thought it might stem from having a Sky block in the mission file that doesn't have the media for stars.dat set yet, so I added that to the mission file manually... and it still crashes. I deleted the sky object then reloaded the mission, and added a new sky... and it crashes immediately.

The .cc and .h files compile just fine, with no warnings or anything. I saw a few other people were having the problem that the star render code crashed when you clicked on the Media tab, but there weren't any resolutions posted.

Can anyone point me in the right direction to figure out what's wrong with the mission file or the code?

Thanks!
