Infopath 2010 form on Sharepoint 2010 unable to save validatioin errors

Hey Experts,

I have a Sharepoint 2010 server running on Server 2008. We have a list that has a custom form created using infopath for editing and new creations.

The problem appeared after a server restart.

Users can no longer create a new item in the list when they do they get this error:

The form contains the following errors:

Field or group: my:Author
Error: Cannot be blank

When I try and preview it in infopath2010 it also does the same thing but provides a more detailed error:

Infopath cannot submit the form because it contatains validation errors that are not in the current view. Errors are marked with a red astrick or red dashed boarder.

If you cannot find an error in otherviews, there might be a problem with the forms design.

I checked all thru the form for my:Author field and can't find it on the page as a control or in the list of fields. Any recommendations?

Thanks!
