What does the error graphcrs.cpp line 1631 mean?

[Godbach]

Hi, everyone. As the title says, when I start LabView8.0, there is a message: The last time you ran LabVIEW, an internal error or crash occurred at graphcrs.cpp, line 1632. And I wonder what's wrong with my LabView, and what should I do in this condition. Rescue or Reintall. And which one is the better.
Thanks in advance.

I am sorry that the error should be in line 1632.
