InfoPath Dev

Some users are getting the error below ======================================================================================= InfoPath cannot create a new, blank form. InfoPath cannot open the form. To fix this problem, contact your system administrator. Form template: https://sharepoint site/Forms/template.xsn The selected file is an update of a form on your computer. However, the update has been blocked because the author of the file cannot be verified. If this file is a legitimate update, use the Fill Out a Form dialog box to remove the original form from your computer, and then open this file. Form template name: TEMPLATE NAME Form template ID: urn:schemas-microsoft-com:office:infopath:templatename:-myXSD-2010-07-27T20-35-04 Form template location: https://sharepoint site/Forms/template.xsn ============================================================================================================= We have published new templates and keep getting this error. Is there something in the form template settings I can change to prevent this error for users? Is my form template addrress incorrect? "Form template: https://sharepoint site/Forms/template.xsn" Also, the error is only received the form is opened from another form , not when we try opening by clicking New on the respective form library. Kindly help if you have any suggestions. Also, not ever user has this problem, but I am not sure.

 Not sure about form templates in sharepoint, or even Infopath 2007, but I found the following avoided my users getting 'form upgrade' messages in Infopath 2003.

When you publish a form, you end up specifying a form name and a form URL to publish to. I always adjust the form name field so that it reads something like <formName>_v#, so the first one might be: myForm_v1 and the next myForm_v2 but I keep the URL/publish address the same (so links etc to the template don't have to change). This has removed any occurances of 'form version' messages for me, and I believe forces Infopath clients to create a new cache for the form every time there's and update.
