It made SQL Server think that the either the Index or the table was corrupted and wouldn't allow us to pull data from the one particular table. The reason we're not having the same problem with the other databases is because those credit card number are not encrypted. We're gonna have to un-encrypt the credit cards stored in SQL Server in order to avoid the problem, again.
