To OP:
Have you made sure to add the database to your list of User DSN's? I originally had a database which I made using MS Office Access added to my list of System DSN's, but I was getting the same exact SQL Exception with the same message that you had as well. But, all I did was add the database name to my list of User DSN's and suddenly the problem was resolved. I figured that this might be your problem as well.
