Question : Cannot open form in Domino Designer

I did a lot of editing on a form called Company, now when I try to open it, I get the error message "Not a form". Is there any way to open it and see the changes, or do I have to start all over?

Working in Domino Designer 7.03 on Windows XP. The database is on a Domino 7.02FP2 Server, running on Windows.

Answer : Cannot open form in Domino Designer

It seems that the form is corrupt.
Have you tried to restart Lotus?

If that doesn't help I don't see what else you can do to fix this.
So you'll have to do it all over again, as you suggested.
