Unable to save CR

Hi All,

When i tried to "save as" or "save" a report, CRW will generate error stating that

An error has occurred in your application.
If you choose Ignore, you should save your work in a new file
If you choose Close, you application will terminate.

When i click any of the button, another prompt came out,

CRW caused a General Protection fault in module CRW.exe

What caused the error? I am using CRW 7.
