Creo cannot open individual parts

I am using Creo Parametric Release 6.0 and Datecode6.0.4.0

A single part (.prt) created by Creo is about 1.5G, 200 arrays, which cannot be opened using the master representation. Open with automatic representation, the appearance can be displayed, but the model tree only displays the part name, no other sub-features (nor the datum plane), and prompts "This view has been frozen because of an illegal view instruction".

Creo创建的单个零件（.prt）约1.5G，200个阵列，使用主表示无法打开。使用自动表示打开，可以显示外观，但是模型树只显示零件名称，没有其他子特征（基准面也没有），并且提示“因为非法视图指令，此视图已冻结”。
