InfoPath Dev

I'm setting up a Data Connection in my InfoPath form but it refuses to connect and show me the available lists in that site.It shows me a login prompt and all my valid logins do not work and it gives the error "Unable to connect to the SharePoint site." At the same time, I can select lists from sites directly above that one...What is going on here??

Hi AlexK,

Did you check that you have enough permissions to the subsite?

I know I have sufficient permissions for two reasons: one is because I was able to publish fine up until today, and secondly because I have admin level "full control" SP permissions on this site. It may have something to do with the Use Profile Service not working correctly though...it may be a SharePoint issue.

This is definitely an InfoPath issue with data connections. ALL of my data connections are broken. I know this because creating a new data connection by going to "Add" allows me to access the site where my form was published to without any problem or any login prompts. Now I have to recreate each of them while referring to a backup. Why would InfoPath kill all of my existing data connections?

 If it were my form, I'd save it as source files. I'd create a new form and create a list data connection to one of the same lists and save it as form files. I'd compare the data connection information in the manifest.xsf and see if I could find out what was different....
