InfoPath Dev

Hello,

   I am new to Infopath and have been developing a few forms and have run into an issue.  My newest version of this form will no longer open as there is a duplicate data connection listed in the manifest.xsf.  The problem is that I cannot open the manifest to edit it.  When I try to open the solution file it gives me the error, if I rename the solution file to a cab and open in VS I can see the manifest and extract it but then cannot get it back into the solution.  Any suggestions would be welcome, I have lost an entire weekends worth of work if I lose this version. 

Any suggestions on modifying this file?

Thank you

1. Copy the files from the CAB folder into a new folder
2. From the new folder, open manifest.xsf with a text editor, like notepad
3. Make your changes, save manifest.xsf
4. From the new folder, try to open manifest.xsf in design mode
5. If the form opens, you can 'repackage' it by using File / Save As to save the form template

Thank you Hillary.  I had just found this solution listed in another post.  Thank you so much, this really helps me out.
