This means the program can't find the parts files in your LDraw library, and the most common reason is either that your LDraw library is corrupted or missing, or that LDCad isn't correctly configured on where to find it.
If you go to menu Prefs->LDraw->Search (library) paths…can you show us what that dialog window looks like?
