InfoPath Dev

I have old forms in 2007 INFOPATH (open in Infopath) published/stored in Sharepoint 2007 from last year.

This year, I modified the template (still 2007 infopath with new new rules and added shrepoint workflow ot it) but in web browser format, then published/stored the form template in another form library in the same sharepoint site.

I received a request to open the form from last year. When I tried to open the old forms, the form opened as a blank form without the data that was entered by users or it cannot open because it syas the .NET Programmability is not working.

I can try to work on getting all the information in the form fields by using property promotion EXCEPT I cannot get the attached file to the form using property promotion.

I currently have infopath 2010 and 2007 installed in my PC.

So, HOW can I open old submitted forms?

Please help ...

Anyone had this issue before???

Well, the first thing I'd do is save one of the old forms (XML files) locally and open it with a text editor to make sure the data is there. There will be information at the top of the XML about the template it is using - probably the template currently published to the library. Then I'd check on the template that is published to the library - is it the correct template? Does it have the correct schema?
