Use one of the following methods to correct this problem.
Method 1
Open the Schema.ini file with a text editor such as Notepad, and then delete the section that you are having trouble with. The section starts with the name of the text file in brackets. For example, if you export the Shippers table, the section would start on the line that has [Shippers.txt]. The section ends on the last line above the beginning of the next section.
Method 2
Open the Schema.ini file with a text editor such as Notepad, and then correct the field names that you are having trouble with. For example, if you export the Shippers table and later change the CompanyName field to CName, you would change the line that read
Col2=CompanyName Char Width 40
to read as follows:
Col2=CName Char Width 40
Method 3
Delete the Schema.ini file, and then export the table or query.
