Thank you for pointing me to these articles, I really appreciate it.

I have done everything in them and I still get the same error when I type in the Password for the data file

It says...

The attempt to login with the username Admin failed.  This user is already logged into the company file.  Try logging in using a different username.

I have no idea how to use a different username, I was hoping changing the service to login with local account was going to fix this but it hasn't.

Any other ideas?
