Sorry couldn't be more help :(https://www.infopathdev.com:443/forums/thread/84332.aspxSat, 10 Nov 2012 00:42:14 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:84332falkata0https://www.infopathdev.com:443/forums/thread/84332.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=142&PostID=84332Just finished making a number of changes to a form template and went to view it in preview mode when I got the error "Infopath cannot open a new form. The form template is not valid. Unspecified error." I tried deleting the changes I made to the form, but even if I delete the whole form and as many of the fields and rules as I can (trying to remove any crippling error source), the error persists and the form cannot be opened. Is it corrupt? I would just copy the form to a new template if there was a way to keep the fields (but of course everything becomes unbound and all default field values erase- how is that remotely helpful?). If anyone has any ideas I would greatly appreciate it. This is Infopath 2010. Thanks.
