At that time I remove the new changes from my InfoPath design form which I made. Then it works properly.<br /><br />Now, In your case, try once by updating the data connection to what it has previously.If you get your .xsn file back then update the data connection which is made for your access data base by using tools-&gt;data connections-&gt;and select the dataconnction which you want to modify-&gt; click Modify and modify the data connection as you required. (I think, it is one way to get back your .xsn file)<br /><br /><br /><br /><br />Unable to open .xsn filehttps://www.infopathdev.com:443/forums/thread/1298.aspxThu, 18 May 2006 09:59:48 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:1298afsabadell0https://www.infopathdev.com:443/forums/thread/1298.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=1298Hello<br /><br />This is surely a newbie question:<br /><br />I've created a form last year, conected to a MSAccess DB. Worked fine.<br /><br />Due to a change in the DB structure, I've had to modify the data source in my .xsn file.<br /><br />Since then I can't open the file, neither in design mode nor in fill-in mode.<br /><br />Error shown says : "yourfile.xsn is not a valid xml document. Bad document syntax, line 1, position 1".<br /><br />The only thing I've changed is the DB link, and though I am newbie in this program, I don't remember any mistake that could have caused this malfunction.<br /><br />Does anyone know if this can be fixed? It's a rather complex form (hidden fields, 2 views, 2 languages) and the idea of create a new one from scratch desperates me...<br /><br />Thank you for your help!
