When I try to open a certain form in my project, I get an error that says "Error loading file - record number 6. Header1 <or one of its members>.Parent : Object class is invalid for this container." The last thing I did was begin to name all of the headers for the columns, but I didn't get finished before I had to save and exit, and now when I try to open it back up to finish naming, I can't get in. Any ideas on how to fix this?
