VS 2010 and Crystal Reports Asks for User Login

I'm not sure if this is the correct place for this but here it goes:

I have several reports built in VS2010 Crystal Reports. When I attempt to view these reports in the report viewer I am asked to enter the database user name and password. The database field is disabled and nothing is in it. No matter what credentials I use they are rejected. Has any one seen this before, does any one have ideas on how to get around this? The OS is Windows 7 and Crystal Reports Redist 2008 v2 is installed.

Thanks in advance for any info!
