Ensure you're meeting these conditions:

 * You're using Microsoft Access 2000

 * You're using version 6.3.91.8 of the Vbe6.dll file are installed on the 
computer, and either of the following conditions is true:

    - You imported forms or reports that contain code modules or standalone 
modules
      into a new Microsoft Access 2000 database by using Microsoft Access 
2000.

    - You copied and pasted forms or reports that contain code modules or
      standalone modules into the Microsoft Access 2000 database by using 
Microsoft
      Access 2000.

  Then, you closed and reopened the database and try to view, execute, or 
compile
  the code.

If these conditions are indeed present, you can obtain the update either 
through your local Product Support Services subsidiary, or I may be able to 
further assist you.

Please let me know if you'd like my assistance in obtaining this update.
