This project was working fine.

The hard drive was going out on my development PC, so I swapped in a new one, reloaded my data, installed SQL Express, loaded my database, and tried running the project.

The form uses SQL authentication, and I have the username and password listed in the connection string and the user is added to the list of users in the database.

I still can't get this to work!

Server Error in '/' Application.

Could someone PLEASE help me?

This is a free job that I do for a local non-profit organization. Though I do not get much time each day to spend on it, I have been struggling with this for almost a week now. I am no closer to resolving this than when I first got the error.
