You can then go to File / Extract form files to extract your manifest if needed.<br /><br />The best way is to reverse the changes you made to your form today until it <br />can be opened again. I hope that you have a backup of the form before you <br />made changes...just in case.<br /><br />Good luck.<br /><br />Regards,<br /><br />Franck Dauché<br />https://www.infopathdev.com:443/forums/thread/4984.aspxTue, 11 Oct 2005 15:56:18 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:4984marks0https://www.infopathdev.com:443/forums/thread/4984.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=4984Have have a form published to our WSS site.
