Data input error

[John Ling]

.dta file corrupt
The file does not record <varnames> where expected. Either the file was written incorrectly in the first place or the file has become corrupted.
When i read the dta file it shows this error.

Where did you get this dataset from?

This data comes from the CSMAR database and comes from China. My data can be used several days before the error occurred, but in my memory, it seems that Stata was forced to close once, and this error occurs when I open it again..
