Form doesn't show data from SQL 2008 Server Express database in VB 2010 Express

Up until a few minutes ago, everything worked perfectly on my form.

I had fields from one of 2 existing Tables on my SQL 2008 Server Express database on my form.

I added a new table to my SQL Database.
I added a new Key to my existing SQL Server Express database Table and deleted the old key column.

Now, none of the data from the existing database Table and data from the new Table will show on my form.
When I click Database Explorer and then click Show Table Data, everything looks normal with the data showing.

What happened and what do I to fix it??
