I am working with an Access 2010 database that I built. I made a copy of the database (because I was unable to save it under a different name to a different file) to a new file. Now when I go into the Main Table I'm unable to make any changes to the fields and/or to add fields. Each time I try I receive the error message Too Many Fields Defined (there are only 82). And I receive the same error if I simply attempt to make the field length longer. Why is this happening and how do I get it to stop and allow to make changes?
Thank you.
