Hello,
I was able to open my form in Designer mode, was able to make changes but when I tried to see the preview in Infopath Filler the program crashes. Also publishing to a SharePoint site went OK. I can open and start forms in web browser from SharePoint library without the problem. Any idea why I cannot check my changes in Infopath Filler before I publish them to SP site? This issue is complitely new to me. Form itself has more than 300 copies on SP server and I have it for more than 8 months.
Thank you!
