[LPub] Parts 2310 and 3386 in LPUB3D

[Pellegrom]

I am trying to use the parts 2310 and 3386 in LPub3D. I have put the parts in the directories:

C:\Users\Public\Documents\LDraw\Parts directory
and  
C:\Users\Public\Documents\LDraw\Unofficial directory

I cann see/use the parts in MLCad but not in LPub3D. In LPub3D the parts shows as a brick 1x1 without a stud on top. It does not show in the PLI at the building step.

Wo cann help me? Thanks for your support!
