InfoPath Dev

Hi All,

I have Infopath 2007 on my system, however, I created a new form and saved it as Infopath 2003. And published the same on Sharepoint form library. When I try to open the form from Sharepoint library, it is working fine. However, users who have 2003 on their system tries to open the form, it says,

Infopath cannot open a new blank form

One or more required controls in this form cannot be created.

I am not sure how to fix this problem. Please help!

You don't get an error when you save it as an IP 2003 form? Nothing in design checker? You aren't using anything that is IP 2007 only, like combo boxes, right?
