Crystal Reports Login continues to popup when report is set to not have a login

I'm working on a crystal report that sorts data and allows your search by entering different names.
I'm using the AdventureWorks access database that was provided by my instructor. With this database he has required us to put everything into one folder then after completing the work to zip the files and post them to blackboard.

My problem currently is within my database connection to my report. When I try to run my report I continue to be prompted for a database login information.
When I first connected my database to my project I selected OLE DB (ADO) like I have throughout my class I ran through the wizard the same way as before and now when my database loads today it prompts for user name and password. While last night when I was working on my project I didn't receive a single prompt.

How does this occur?

What file controls the database access information. As there is now user name and password how does crystal reports just assign something to it?

I need some helpful hints in where to look or what steps should be taken to resolve this problem.
I'm also not receiving any errors when I build my project.
