Problem with parts not showing on Parts list box

[Jaco van der Molen]

I had the same issue with the same part. I have updated the unofficial part list, but now LDGLite keeps crashing...

Any tips?

Sounds stupid perhaps, but to solve it, do not use LDGLite. Though fast and still functioning LDGLite is a bit outdated and not quite up to date.
Try LDView as renderer. Nearly as fast, if not faster and better quality images.
